[Dovecot] dsync-local(user): Error: proxy client timed out

Hello, I have an intermittent but frequent problem using dsync backup. The command outputs: dsync-local(user): Error: proxy client timed out Then dies with exit code 75. Any subsequent attempts to re-run the backup invariably fail like this: dsync-local(user): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync-local(user): Error: read() from worker server failed: EOF dsync-local(user): Error: msg-copy returned invalid input: dsync-local(user): Error: remote: dsync-remote(user(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(l_user(a)domain.com): Error: command MSG-SAVE failed dsync-local(user): Warning: Mailbox changes caused a desync. You may want to run dsync again. The syntax I am using is: dsync -u $user backup \ ssh -i <idfile> <user@host> \ dsync -u l_$user We have this running in a script that loops through all users. The error happens mostly on the larger mailboxes but I've seen it succeed on the largest ones then fail on smaller. One mid-sized account now fails consistently. The backup is running from a Mac OS PPC server running 2.1.12 The target is a Linux Intel box running 2.1.13, but I had the same problem sending to a Mac OS Intel on 2.1.12. Mdbox in all cases. Thanks, Tony

According to the roadmap http://wiki2.dovecot.org/Roadmap implementation of the METADATA / ANNOTATE extensions is fairly high on the list. I was just curious if there is a target release in mind for this functionality?

[Dovecot] Overloading IMAP Server
by Harford, Ken 04 Feb '13

Hi All, I am having an issue with dovecot IMAP reading and writing to one specific mailbox. I have a check email delivery script that sends out a email and then logs into dovecot to check if the mailbox that the message has been delivered to. However, the servers that send these messages send them in bunches depending on how many postfix spools it is checking. So I could get 60 messages all being sent to 1 mailbox and then having to read that same mailbox to check if the message actually got delivered. I am using postfix as the MTA and dovecot is actually delivering the message to the mailbox I am getting a lot of errors such as the following: Could not connect to IMAP server imap failed: IMAP RECEIVE CRITICAL - Could not select INBOX Any ideas as to what I can tweak in dovecot to allow these messages to be verified. Thanks for any information or help you could provide!! Ken

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
by Ben Johnson 01 Feb '13

01 Feb '13

Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox -> Junk (or Junk -> Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben
