Today we are run tests with direct send and domain key sign.
The first tests with small mails are successful but then we are send bigger mails and the receive server said signing is invalid. As example send a mail with more than 2000 chars. The DomainKeysSign runs without errors. If it strange as the content of the mail is not relevant for signing.

We are need this for sending our newsletter.

mailer.Message.DomainKeysSign(false, null, @"C:\Temp\rsa512.private", true, "dk", DomainKeysTypes.Both);

Update:
I have read the documentation of DKIM and the body of the mail is also relevant.

Well, we have never had any issues with DKIM, regardless of body size. I'd suggest to try reproducing this in terms of a single, non-loop example to eliminate chance of any bodies/attachments reused from previous iterations.

But, do you have any issues with one single mail sent out?

This doesn't actually seems to be caused by MailBee, but rather by SMTP server used by either party. As a wild guess, I'd suggest to check whether the message might be altered by some antispam and/or antivirus software, comparing the message which is sent out with its copy obtained by the recipient might help.

Just to clarify my previous question - can you get a reproducible behavior with any specific mail message, so if check fails for it, it fails on any subsequent sending attempt for the same message?

Thanks for the code. Indeed DKIM fails with this sample. Will work through this out and let us know when we find the solution.

Alex

What happens if you run the sample multiple times. In our tests, dkim failed only once but running it another time (and 3rd, 4th, etc) no longer produces any issues. I.e. the problem is not reproducible.

Alex
