Attachments get lost when fetching signed mails about mailsystem.net HOT 4 CLOSED

Hi @domshifter !
I never heard about this issue.
Can you give to us the steps to reproduce the problem?

from mailsystem.net.

Hi @reinaldocoelho , thank you for your fast reply!

We used Comodo to generate a certificate which we then used to sign the mails.

I tested three scenarios:

1. Send a mail from my dev machine, then fetch it with my application which also runs on my machine. This works (maybe because i got the certificate installed on my machine which i used to sign the mails?)

2. Send a mail from my dev machine, then fetch it with my application on another dev machine which is in the same domain. This also works.. (maybe because the two pc's are in the same domain?)

3. Send a mail from outside our domain, then fetch it on my local running application. In this case, i'm not able to get the attachments.

Our code looks something like this:

_client = new Imap4Client();
_client.ConnectSsl(settings.ServerName, settings.Port);

var inbox = _client.SelectMailbox("inbox"); 
var messages = inbox.SearchParse("ALL");

foreach (var message in messages)
{
    foreach (MimePart attachment in message.Attachments)
    {
        //process attachment
    }
}

_client.Disconnect();

@domshifter only the attachments is out of message?
Can you get both EML files and attach to this issue to compare that?

You can use the methods Message.StoreToFile() or Message.ToMimeString().
