Hi!

I think I found one pretty much serious bug... Messages sent via webmail, to external recipients which are having . (dot) in their email, can't be sent when you first push the send button, only on subsequent retries. Here's what I get in web mail, why postfix sometimes rejects messages sent through webmail?

Anyone managed to solve this problem? Or at least make workaround? Thanks!
