Emails with trailing underscores are falsely identified as invalid about email_address HOT 7 CLOSED

Ah, I see. The address tag could be any reasonable set of characters, but the mailbox part (lloyd) would need to conform. Standard format will work, but may be too lax for user email addresses. Upcoming work should address this better, I'll see what I can do for this branch.

Hi,

Yes addresses ending with an underscore is RFC-compliant, but "suspicious" as a well-formed user address in what we call "conventional". You can add local_format: :standard as an option to the valid?() call which will consider your address as an RFC standard address.

Is this address from a large email provider (google, msn, yahoo, aol ,etc)? Those shouldn't end in the underscore, but private mail hosts can do anything, but still seem suspicious as a "formal" personal address. I may need to reconsider such formulations.

I also recently ran into this (a hotmail address). As of the last time I checked, outlook.com lets me create emails with trailing underscore.

I'm seeing a similar error with a hyphen:

2.6.5 :003 > email = '[email protected]'
 => "[email protected]" 
2.6.5 :004 > ::EmailAddress.new(email).valid?
 => false

local_format: :standard works just fine! Thanks.

Hi
I am on Angular

And using the below regex:

'^[a-z0-9]+([._-]?[a-z0-9]+)+@[a-z0-9]+([._-]?[a-z0-9]+)+\\.[a-z]{2,3}$'

But its not fulfilling my requirement, my requirement is below:

please anyone tell me, why this regex is not working for my above mentioned case.

Your problem is the \. in the match which needs to only be . to match a period. \. Will match a \ followed by any character.
Search the web for a "regex tester" to build it interactively.

BTW, this is not a good regex for email because it is too simple to cover most cases. Also, _ is not allowed in domain names.
