If you only want to dump a few auth cache entries, you can just authenticate with a bad password. When a different (and possibly correct password) is supplied, there will be a cache miss and the new credentials will be cached. echo "1 login someuser badpassword\n2 logout" | netcat --ssl your-imap-server:993 Joseph Tam <jtam.home(a)gmail.com>

migration from cyrus with dsync sieve problem

Exit status code 134; what is it, in the context of Dovecot Antispam plug-in?
by Ben Johnson 17 Sep '14

17 Sep '14

Hello! I just migrated from Ubuntu 12.04 LTS to 14.04 LTS and thereby from Dovecot 2.0.19 to 2.2.9. I've been using dovecot-antispam plugin with great success for the past year with 2.0.19, but after this migration, I've been seeing the exit status code 134 in the syslog when attempting to debug the Dovecot Antispam plugin not working after the migration. I have some debugging output in my pipe script; the output looks something like this: Copying message contents to temporary file for debugging purposes; file is: /tmp/sendmail-msg-7662.txt Checking if the command-line input argument string (--spam) contains the string "ham" or "spam" Mode is "SPAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-7662.txt"' Exit status was 134 Yet, I'm able to copy the above command and execute it manually, via the command-line, and it works (and by "works", I mean to say that the behavior is correct and exactly as expected; I receive the "Spam" email at the designated mailbox). Here's how I'm calling it when it works perfectly well (as "root"): # su -c '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-7460.txt"' vmail Any idea what status 134 might be or how to work around it? It looks to be some kind of "temporary failure exception", but that is less than informative in this context. "doveconf -n" output is appended.

replicator only starts for users who log in at least once
by Alan McGinlay 17 Sep '14

17 Sep '14

Hi! I recently setup a second with replication to the other. Both machines run ubuntu 12.04 with dovecot 2.2.13 (6bb26098a45c). All users mail accounts are currently synced manually to the first (mb1) using a dsync script, they are synchronised from a cyrus imap server. Users are still logging into the cyrus server. It appears that the only accounts that are replicated are ones who have logged into either of the dovecot servers at least once, is this how it is supposed to work? I was hoping to get full replication of all mail accounts before starting to move users into the new system. Thanks, Alan

Case sensitivity
by John Oliver 15 Sep '14

15 Sep '14

I think I've answered my last question by changing mail_location But I'm still getting duplicate mailboxes: [joliver@localhost ~]$ sudo ls -l /var/vmail/ total 8 drwx------. 3 vmail vmail 4096 Sep 11 10:30 testuser1 drwx------. 3 vmail vmail 4096 Sep 11 10:36 testUser1 The cn for my user is 'testUser1', and that's where postfix writes mail. But dovecot wants to use 'testuser1', even if I log in as 'testUser1' I suppose one answer may be to try to get postfix to always use lower-case, but in case that can't happen, how can I get dovecot to ignore case when looking for mailboxes? -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************
