migration 1.2.5 -> 2.0.5 load increased dramatically
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

Startup error dovecot-2.0.5
When starting 2.0.5, I'm getting:
# /usr/dovecot-2/sbin/dovecot -F
doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288)
doveconf: Fatal: execvp(/usr/dovecot-2/sbin/dovecot) failed: Argument list too long
Argument list too long? WTF?

Why does 95 exceed 128?

Login with firstname.lastname instead of loginname - WORKING
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.

Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings)
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:

"try MD5-CRYPT scheme instead"?
I'm getting a lot of entries like this in my log:
Apr 16 10:10:18 postamt dovecot: auth(default): shadow(doxxxris,141.42.206.38): CRYPT(wrongpassword) != '$1$qSe71xxx$09MoMqNyll.wPLCdSaFuA0', try MD5-CRYPT scheme instead
It seems that changing the password via SquirrelMail (poppasswd)
breaks the authentication scheme somewhat. Users cannot log in anymore.

Implications of zlib plugin on search operations
Right now I'm compressing all mails older than 31 days and larger than
100k in size.
But what implications does this compression have on search queries
performed by users (user looking for an old mail containing a certain
string).

imapc Proxy to IMAPS Exchangeserver?
I'm trying to adapt http://wiki2.dovecot.org/HowTo/ImapcProxy
to our Exchange Server, which has LOGINDISABLED on Port 143, and I
offering LOGIN on Port 993.
How do I go about this?
Simply changing imapc_port to:
imapc_port = 993
doesnt work:
Connected to localhost.
