• [V ] I have read and understood the FAQ

Describe the bug
I got the AttributeError: 'SMTP' object has no attribute 'sock' when I run the validate_email()

To Reproduce
Run the validate_email() to varify an email

Expected behavior
I expected it will return either True, False or None

Desktop (please complete the following information):

• OS: Linux
• Your network environment (ISP provided home connecton, or testing from an actual whitelisted server)
  I use colab to code

As documented in #18, my ISP blocks port 25. Similarly, Amazon also blocks port 25 by default.

When I try port smtp.gmail.com:587, it wants TLS:

09:36:19.037743 send: 'helo smtp.gmail.com\r\n'
09:36:19.089443 reply: b'250 smtp.gmail.com at your service\r\n'
09:36:19.089573 reply: retcode (250); Msg: b'smtp.gmail.com at your service'
09:36:19.089910 send: 'mail FROM:<[email protected]>\r\n'
09:36:19.137085 reply: b'530 5.7.0 Must issue a STARTTLS command first. h19sm1787816qtk.78 - gsmtp\r\n'
...

It might be useful to support TLS if it were easy, though I don't know enough to say for sure.

waiting for update

Hi! We found another bug in one of our staging servers.

We use Python 3.8 and call SMTP. connect without specifying hostname in SMTP class constructor, we will get Value Error with this traceback

I will create PR today to fix it

Dear contributors, I have the following suggestions after I made my research about other email validation API:

1. Detection of the catch-all property of the email server
2. email spam traps detection
   I am not sure how to do these functions so I can't make a PR, if you know and share any resources about how to implement it, I can implement it for the project as well
   Thank you

Hi,

I have seen this error been posted before. It seems to be a problem with the mac / virtualenv setup?

Hello.

Thx for your library :)

I'm using your module in the AWS Lambda. There are some limitations there, one of them is that the filesystem is R/O with exception to the /tmp dir.

When I ran:
validate_email(email_address=sender_email, check_regex=True, check_mx=True, dns_timeout=10, use_blacklist=True)

got:
[Errno 30] Read-only file system: '/opt/python/lib/python3.8/site-packages/validate_email/data'

Is there any way to specify temporary dir or maybe keep this in memory?

Regards

how many requests can we do a minute / time periode before getting banned?

Hi,

just tested your package and got that reply.

I am getting this error using Windows 10 and Python 3.7.4

I use your module in a command-line utility I've written for our company, every time it starts we get the spitted out info for the blacklist check. We would really appreciate a way to disable this output.

See below:
(note that the '::>' is all you are supposed to see. Its the 'promt' part of the utility but its being covered by the output of blacklist check. My users are confused because they think its still doing something and it is not.)

Hi First of All let me thank the developers for their time on this project but I seem to have found a roadblock and wanted to know if there is any way I could check if the false negative can be weeded out of the validate_email.

Here is my code:

from validate_email import validate_email
is_valid = validate_email(email_id, check_regex=True, check_mx=True, from_address=test_email,
                          helo_host=em_domain, smtp_timeout=10, dns_timeout=10,
                          use_blacklist=True, debug=True)

Basically I am trying to validate a lot of emails and most of them are getting great responses but only in case of Yahoo or Rediff I am getting false negatives since all the email IDs are being flagged as invalid. Here is the small debug for the rediff email, I am masking the actual emails since we are on public domain for privacy related issues

Hi,

I just tested the package and it keeps throwing the following error with the sample code that was provided. I am running Python 3.7 and the package version is up to date.

Hi,

Most email providers reject Port 25 now.
It would be a nice enhancement to be able to test email by using secure SMTP Connection (eg : Port 465 or 587).
It's also mean to be able to use a real email account and providing user+password (so extend py3-validate-email SMTP part).
For exemple, i like to use a gmail account to test emails.

The mx_check() function inside mx_check.py catches all ValueError exceptions and it just returns False with no additional information on what the error is.

I was having some trouble validating a hotmail.co.uk email address (the address exists and is valid) and as I was tracing the error, I realised the above.

Is there a way to add logging to the mx_check() function when handling the ValueError so there is visibility on the actual errors which caused the validation to fail?

I got this error when trying to install it on ubutnu 18.04, python 3.6.9

Hi I Tried This Module But It Only Work For Gmail It's Not Working On Yahoo,Outlook,hotmail

here is the code

validation = validate_email(email_address=str(df[i]).replace(',','').replace(';',''),check_regex=True,check_mx=True, from_address='', helo_host='', smtp_timeout=30, dns_timeout=30, use_blacklist=True)

Thanks for your library.

I tried it with a simple email I know exists, and it timed out as follows:

$ echo "[email protected]" | ./validate_emails.py 
Validation for '[email protected]' failed: Email address undeliverable:
ASPMX3.GOOGLEMAIL.com.: timed out
ASPMX2.GOOGLEMAIL.com.: timed out
ALT1.ASPMX.L.GOOGLE.com.: timed out
ASPMX.L.GOOGLE.com.: timed out
ALT2.ASPMX.L.GOOGLE.com.: timed out

My call is straight from the docs:

        is_valid = validate_email(
            email_address=the_email,
            check_regex=True,
            check_mx=True,
            from_address='[email protected]',
            helo_host='smtp.gmail.com',
            smtp_timeout=1,
            dns_timeout=1,
            use_blacklist=True)

How do I further debug this?

It may well be a firewall somewhere, but I can't tell where those hosts come from, or which line is timing out.

When looking through the code, I noticed that sometimes the same task is done in different ways:

• mx_check uses EMAIL_EXTRACT_HOST_REGEX to split the email address into user and domain, while validate_email uses a simple rsplit('@', 1).
• mx_check uses the idna library to resolve IDNA hostnames, while validate_email uses a simple encode('idna').

I could find no reason to not always use the simple method, which probably would make the code more understandable.

Hi Team

how i can check if my ip is blacklisted for checking email validity?
ii want to grep the response code like 250, 251 , etc in variable ? currently its grepping only True , false and NONE .
how i can achieve that ?

Exception 'AddressNotDeliverableError' is thrown both for when a server is blocked/denied and when email doesn't exist.

Gmail allows local testing if you run the following code

try:
    is_valid = validate_email_or_fail(email_address='[email protected]', check_regex=False, check_mx=True, use_blacklist=True, debug=True)
except Exception as ex:
    message = f"An exception of type {type(ex).__name__} occurred. Arguments:\n{ex.args}"
    print(message)

Inside Debug Log it will emit 'The email account that you tried to reach does not exist'

Outlook disallows local testing if you run the following code

try:
    is_valid = validate_email_or_fail(email_address='[email protected]', check_regex=False, check_mx=True, use_blacklist=True, debug=True)
except Exception as ex:
    message = f"An exception of type {type(ex).__name__} occurred. Arguments:\n{ex.args}"
    print(message)

Inside Debug Log it will emit 'Access denied, banned sending IP'

'AddressNotDeliverableError' exception cannot be both if a server got blocked and email doesn't exist.

I'm using a pipenv to run my project's environment in Ubuntu with supervisor.
On start, I'm getting OSError: [Errno 9] Bad file descriptor pointing to line 89 in updater.py
with open(self._lock_file_path) as fd:
Adding a simple 'w' helped resolve the issue.
with open(self._lock_file_path, 'w') as fd:
Can we add this to the library or am I missing something?

This package runs fine in development but in production, looks like something may be blocking it. I double-checked my firewall rules and seems for outgoing traffic. Has anyone ever seen this?

Thanks!

is it possible to separate check_mx to check just the MX record and not whether the email actually exists?

I'm not sure I completely get the "Everything gets rejected" part. I have a custom email address on an SMTP host (Mailjet).

I've put 'helo_host' = 'in-v3.mailjet.com' and 'from_address' = 'my_custom_email_sent_from_helo_host' as well as opened port (25) to no avail. Any ideas?

On a fresh install, where blacklist.txt is not yet present, BlacklistUpdater.process() fails because it tries to lock that non-existent file.

I see that setup.py should run BlacklistUpdater.process(), but it doesn't, at least not when installing with pip install. And if it would, it would obviously fail for the same reason anyway.

On a side note, I think that putting the updateable file inside the validate_email directory might lead to problems because on a system install, that directory might not be writeable for the process that actually runs the code.

py3-validate-email requires specific versions of its dependencies, but for two of them newer versions would be available:

• dnspython: 2.0 required, 2.1 available
• idna: 2.10 required, 3.1 available
  Maybe the requirements list should be updated before the release. From a look at the version statistics, none of the updates seems to contain any change relevant for us.

Hi Karolyi

thanks for the fix ..
now i can see exceptions are getting logged .but just want to know about the format of exception.
you can see Error code 554 is only getting displayed in the log properly. where as in 2nd case mention below , format seems to be not showing error code, can you please comment for the same.

1)Correct format
2021-02-09 03:52:10,145 ["hostmx01.logix.in: (554, b'pune2.logix.in\nIP blacklisted in http://www.senderbase.org')", "hostmx02.logix.in: (554, b'pune2.logix.in\nIP blacklisted in http://www.senderbase.org')"]

2)doubt about the below format
2021-02-09 03:52:04,534 ['mx2.zoho.in: RCPT TO failed: 5.1.1 <a.s*****@.co.in> User unknown', 'mx.zoho.in: RCPT TO failed: 5.1.1 <a.s@.co.in> User unknown', 'mx3.zoho.in: R

I don't know why .. Could you help me ?

Hi,
I have an issue where running validate_email on my private email address does not work. I am able to successfully verify public domain addresses (i.e. @gmail.com etc)

So, if I run validate_email on any addresses @stumbra.co.uk (my personal domain), it can find the MX records, but it appears that its telnet attempts fail.

Input:
>>> print(validate_email('[email protected]', check_mx=True, debug=True))

Result:
DEBUG:validate_email.mx_check:Trying hermes.hosts.co.uk ...
DEBUG:validate_email.mx_check:Trying athena.hosts.co.uk ...
None

The issue appears to be that it cannot connect to them over telnet, and excluding domains where telnet fails with check_mx flag doesn't make sense. While I could do a check where if validate_email returns None to run it without the check_mx flag, I feel like that could lead to false positives.

Any advice/suggestions?

When I check "hotmail" emails ([email protected], [email protected], ...), I always get a 'TimeOut' socket error.

    import logging, sys; 
    from validate_email import validate_email
    logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)
    print(validate_email('[email protected]', check_regex=True, check_mx=True, debug=True))

Got :

WARNING:validate_email.validate_email:Validation for '[email protected]' failed: Email address undeliverable:

Every email I try and verify times out and then fails. Can't figure out what I'm doing wrong

Other things of note:

I had a lot of trouble getting dnspython installed. Maybe its running, but not actually installed properly? It seems to work when I do a simple socket.gethostbyname_ex() though.

Hunter.io has no problem verifying the email address:

Hi!
We found some issues with organization emails located on google suite.

Some accounts in these organizations cannot send or receive emails. So if we try to send a registration email on it, we get a bounce on AWS SES.

How do you think, is there any way to check these email addresses?

There are parts of some AWS bounce notifications:

[{"emailAddress":"MASKEDUSEREMAIL","action":"failed","status":"5.7.1","diagnosticCode":"smtp; 550-5.7.1 This message has been rejected as this student is not able to send or\n550 5.7.1 receive external mail. - gcdp g5si1130787uad.263 - gsmtp"}],"timestamp":"2021-02-18T16:49:33.000Z","remoteMtaIp":"173.194.209.27",

Script i was used for testing

from validate_email.validate_email import validate_email
import argparse

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("email", metavar="email")

    args = parser.parse_args()

    is_valid = validate_email(
        email_address=args.email,
        check_regex=True,
        check_mx=True,
        from_address="[email protected]",
        helo_host="my.host.name",
        smtp_timeout=10,
        dns_timeout=10,
        use_blacklist=True,
        debug=True,
    )

    print(f'RESULT: {"Valid" if is_valid else "InValid"}')

Replaced the previous validate-email package with py3-validate-email.
However, validate_email() returns None for my mail Id.

Hi, quick question regarding validation from my HTTPS EC2. I'll start by saying all works perfectly locally, so I'm wondering if you've had this issue before or have any tips when using on AWS.

I have opened port 25 on my ec2's security group for all inbound requests (all outbound requests open as well). Additionally, I can send emails using Gmail's smtp server successfully from my EC2. In the mean time I have contacted AWS to ask if there are any restrictions in place that they can lift. Below is my error:

>>> validate_email(email_address='[email protected]', check_mx=True, from_address='[email protected]', helo_host='smtp.gmail.com', smtp_timeout=10, dns_timeout=10, use_blacklist=True, debug=True)

Any help is greatly appreciated (note: I have also read through the other issue on the repo #19).

Thanks!

for use in aws lambda, where data is not persistent

1. allow disable of update completely
2. allow override of path using lambda function for efs
3. or support storing of update on s3

Coming from #5, the library provides positives for yahoo.com addresses where it shouldn't.

Thanks for the great work putting this together. I am having issues making it work, I did a first trial with my own email address and it returns that it cannot be validated. Can you please advise?

from validate_email import validate_email
is_valid = validate_email(email_address=my_gmail_address, check_regex=True, check_mx=True)

Validation for my_email_address failed: Email address undeliverable:
alt2.gmail-smtp-in.l.google.com.: [Errno 99] Cannot assign requested address
alt3.gmail-smtp-in.l.google.com.: [Errno 99] Cannot assign requested address
alt4.gmail-smtp-in.l.google.com.: [Errno 99] Cannot assign requested address
gmail-smtp-in.l.google.com.: [Errno 99] Cannot assign requested address

With the growing number of checks that can be switched on and off, the parameter list has become somewhat long and cluttered, switches are named use_*, check_*, or skip_*, and also some have to be set to True to enable a test, some to True to disable the test.

I had the idea of replacing all these parameters with a single one:

First, we define a constant for each of the possible checks:

CHECK_FORMAT = 1
CHECK_BLACKLIST = 2
CHECK_MX = 3
CHECK_SMTP = 4
CHECK_SMTP_COMMUNICATION = 5
CHECK_SMTP_TEMPORARY = 6

and we define the default set of checks as a Python set:

CHECK_DEFAULT = {CHECK_FORMAT, CHECK_BLACKLIST, CHECK_MX, CHECK_SMTP}

Then, we can change validate_email_or_fail to accept the parameter checks: Set = CHECK_DEFAULT.

Downside: this would either break compatibility with previous versions, or we'd have to accept both options for a while, adding a deprecation warning when the old parameters are used.

What do you think?

I noticed a small inconsistency, which I consider not urgent or important at all, but still wanted to note it:

While the 'regex' checker spends extra effort for accepting email addresses lke example@[1.2.3.4] as well, the 'mx' checker will refuse such addresses because the dns lookup will find no domain server for [1.2.3.4].
