[Dovecot] Slooow imap copy to "Sent" folders
Hello
Many users here use the "copy to Sent folder" using the IMAP protocol with Dovecot 2.1.15 on a FresBSD 9 server.
Since few days this operation ( copy to sent folder ) became longer than before , it could takes several seconds to complete even the message is very short.
Is there a parameter I could tweak to boost this a bit ? may users complain with reason
thank you
We have a monopoly ISP who gives terrible upload speeds in their internet packages. it is pretty easy for most offices to flood the upload side of the connection, and when that happens we see the symptoms you describe. Not sure if that is applicable to you, but that is what I check when I get these reports...

We deal with a lot of large attachments, so I can't wait for the new 'Submission' agent in dovecot, which will allow someone to write a plugin that will leverage it to automatically save a copy of all sent messages to a designated Sent folder (like gmail does now)... then you can simply disable the 'Save a copy of sent messages to the server' for your dovecot account (if this option is enabled) and it happens automagically from then on.

Do you have access to the MTA your users are submitting their mails to? If so, you could add the sender as BCC / envelope recipient with a default folder to drop off the message, e.g. with sub addressing "sender+Sent@sender-domain".
Well, because you need to reconfigure each MUA, you could add the BCC there.
That way, the message is transmitted only once and has the message queueid in its header for debugging purposes.
