Just a few days ago I sent a file to someone on my same mailserver who then reported the file corrupt and sent it back to me (where I also verified it corrupt). I use Thunderbird to send and they use OE to receive. Postfix + Dovecot 1.1.3 I personally suspect Thunderbird, but it's possible that it is related to Dovecot Certainly I occasionally receive emails from external people which also appear to have corrupt attachments until resent (usually PDF, but that's also mainly what I receive). These would be sent from probably a MS Exchange using Outlook, and received here by Postfix+Dovecot+Thunderbird I can basically confirm the same intermittent issue, but not where it's coming from Oh, some wild thought occurred to me - check the actual files on disk. ie go into the server and grab the actual "corrupt" message from disk and call it something.eml - then you can double click it on a client machine and it should open in the default email program and you can then prove that it wasn't the imap/pop delivery which was corrupting the message. This still means it could be either the MTA or the delivery agent, but I think it will vindicate Dovecot? Regards Ed W
