[Dovecot] Dovecot/IMP attachment problem
I recently installed dovecot in my production environment. This comprises about 60k mailboxes.
The system was initially set up with dovecot 0.99.10.7 using maildirs. I have been using perdition to handle redirection during the process of converting from wu-imap.
Last week it was brought to my attention that our webmail interface (horde/imp) is no longer allowing people to download attachments. Everything appears to work fine, however the downloaded files are 0 bytes in size.
I built a test box with the latest horde/imp/php combination and that failed to solve the problem.
Today I upgraded dovecot on one of our mail servers to 0.99.11 and that seems to have had no effect. I was hoping that the BODY and BODYSTRUCTURE changes from 99.10.8 would have fixed this.
I am wondering if anyone has encountered these problems? Is this a dovecot bug?
Due to the fact that I am still in transition mode using perdition I am in the unique position where I can basically hit two identical mailboxes, one in wu-imap and the other in dovecot just by using a different username. I have done this, and have ethereal traces if anyone is interested in helping me out with this.

No, this is a horde/imp bug. The outgoing mail has no attachement, test it by sending it to an external address.

Well, the attachments do exist in the mailbox, and sending attachments is no problem.
Retrieving attachments through OE->dovecot works, OE->wu-imap works, IMP->wu-imap works, however the combination of IMP->dovecot seems to cause a problem.
I have a feeling that IMP is using a different method of retrieving the attachments than OE does, and there is probably something IMP does not like about dovecots responses.
I will go through my ethereal traces and see if I can piece together what is going on in more detail.

Ok, that may not be a problem with IMP in that case ; I told you that because there was some time ago a well known bug of IMP with attachments, and I have seen it myself when I was using uw-imapd.
