similar to: Deduplication active - but how good does it perform?

Today I was looking for some spam and issued this command: ========================================================== doveadm import -u restore at backup.invalid mdbox:/home/copymail2/mdbox INBOX header Reply-To bixrs.com Then I immediately got a crash: doveadm(restore at backup.invalid): Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset): assertion failed: (offset <

How exactly is LMTP proxying supposed to work? According to the example on http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I'm only seeing "proxy" in the password_query statements. But LMTP never sends a password. IMAP Proxying is working OK: Sep 24 12:51:09 imap-login: Info: proxy(ralf.hildebrandt at charite.de): started proxying to dovecot.charite.de:993:

I set up system copying all mails to a backup system. This used to work without a hitch - now in the last few days mails would pile up in the Postfix Queue, waiting to be delivered using the lmtp transport into dovecot. So dovecot was being slow, but why? After all, nothing changed. After reading some articles on stackoverflow I found a way of finding out which file gets the most IO: % sysdig

I'm seeing the first occurence of that problem on the 10th of october! I was using (prior to the 10th) : 2.3.0~alpha0-1~auto+371 On the 10th I upgraded (16:04) to:

I need to find all mails with a certain numerical range in my quarantine: X-Spam-Status: No, score=4.5 tagged_above=2 required=4.6 ... Assume I'd be looking for 4.5-6.0; so I tried searching for doveadm import -u restore mdbox:/home/quarantine/mdbox "" \ mailbox INBOX header X-Spam-Status "No, score=4.5" doveadm import -u restore mdbox:/home/quarantine/mdbox

Some of our users use to login as firstname.lastname or firstname.lastname at charite.de instead of using the "correct" "flastname" login name. In order to get this behaviour a long-gone co-worker wrote an authdaemon.pl, which speaks the courier-authdaemon protocol. How can I emulate this behaviour with dovecot? Basically, all I need is a usernamen mapping ala:

My users say that "greetings of the day" occurs in academic spam a lot. Since I don't trust my users, I opted to verify this bold claim. But how do I search for a sequence of multiple words? doveadm import -u restore at backup.invalid mdbox:/home/copymail/mdbox "" mailbox INBOX BODY "Greetings of the day" doveadm import -u restore at backup.invalid

For archiving purposes I'm delivering all addresses to the same mdbox: like this: passdb { driver = passwd-file args = username_format=%u /etc/dovecot/passwd } userdb { driver = static args = uid=1000 gid=1000 home=/home/copymail allow_all_users=yes } Yet I'm getting this: Jan 3 19:03:27 mail postfix/lmtp[29378]: 3THjg02wfWzFvmL: to=<firstname.lastname at

Hi! I upgraded the 2.2 packages today (from 2:2.2.28-1~auto+5 to 2:2.2.28-1~auto+8) I now I'm getting an error: Mar 20 13:25:58 mproxy dovecot: auth: Error: imapc(email.charite.de:993): Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) I checked, and alas, I had ssl_client_ca_dir = ssl_client_ca_file = So I set:

3 years ago (!) I aksed about this and finally I implemented it today: >> # NEW >> passdb { >> driver = passwd >> # firstname.lastname at charite.de:password:uid:gid:(gecos):home:(shell):user=realloginname >> args = /usr/local/etc/dovecot.login_via_email >> } >If you're only using it as a passdb, you don't need the uid/gid/home.

Currently I'm having massive problems with LMTP delivery into dovcot. dovecot/lmtp processes are piling up, eas using considerable amounts of CPU: # ps auxwww|fgrep dove root 20537 0.0 0.0 18124 1196 ?

During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25). Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade? We're using Maildir Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage
