Worker-server timeout
Hello Everyone,
First wanted to say thanks for any help in advance.
I have a clustered mail system each running on centos 5.2. I have a
test box that I am running the newest version on dovecot on and I am
getting some random authnication failed errors. Here is the error below:
Nov 04 17:31:22 auth(default): Error: worker-server(xxx at xxxx.com):

Can you use both ssl_protocols *and* ssl_cipher_list in the same config
(in a way that's sane)?
ssl_protocols (>= 2.1)
and
ssl_cipher_list
co-exist, or are they mutually exclusive?
I have a Dovecot 2.2.13 system, and I tried setting:
I also tried things like
ssl_cipher_list = HIGH
or
ssl_cipher_list = HIGH:!MEDIUM:!LOW
however, doing this seems to make v3 still work unless I

Correct settings for ssl protocols" and "ssl ciphers"
I have the following two settings in my "10-ssl.conf" file
# SSL protocols to use
ssl_protocols = !SSLv2
# SSL ciphers to use
ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL
I have seen different configurations while Googling. I am wondering
what the consensus is for the best settings for these two items. What
do the developers recommend?
Thanks!

Mails don't get deleted after POP3
Hi, there!
Well, I am new to dovecot, so please be patient with me:
I have a virtual server and want to setup simple mail delivery.
postfix, saslauthd and dovecot basically work fine.
The only open issue is, that (I guess) dovecot doesn't remove the
mail when it's retrieved via pop3 from the server.
It keeps sending me the same emails again and again.
(The mail client (Thunderbird) is

force ciphers order for clients
Hi Timo,
reading this
http://www.kuketz-blog.de/perfect-forward-secrecy-mit-apple-mail/
it looks like DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA can be forced in use
with apple mail
( if no ECDHE is possible ,by missing openssl 1.x etc,
seems that apple mail tries ECDHE first if fails its going to use
RSA-AES128-SHA )
force soltution as tried

Max IMAP fodlers
Is there a way to limit the amount of maildir folders a user can have?
Also is there is hard limit on the amount of folders dovecot can handle? I have a user who has over 3000 folder (including subfolders) that is having issues with delays in loading, moving, and deleting messages.
Thanks in advance

sieve addflag has stopped working
Dovecot 1.2.10 in Debian, using Dovecot sieve.
I have a sieve script, generated by Ingo, that's supposed to mark spam messages
as "Seen" and file them into the Junk folder. In part it reads:

fts_solr on debian lenny dovecot 1.2.15
Hello,
I cannot run FTS SOLR engine. OS is debian lenny. I re-compiled debian
package (from backports) with --with-solr option. Dovecot loads fts_solr
plugin. I know that it loads plugin because if I remove lib21_fts_solr_plugin.so, dovecot does not start. But it does not attempt to communicate with SOLR.
Simple check: stop solr tomcat, and open 8080 port in netcat:
$nc -l -p 8080

Sharing all mailboxes and userdb LDAP attrs
Hello all,
I'm setting up a Dovecot environment here, version 1.2.15 on Debian 6.0.2

in-place here, built from the ground up with updated versions of all
involved software.
The operators have told me that they use some scripts hacked up by a

Store outgoing mail in users mailbox
This might be a MTA question, but because I use Dovecot as an LDA, maybe
some can help me here.
Our users would like that outgoing mail is automatically saved in some
folder, say Sent. We use Postfix with virtual domains, Maildir and
Dovecot+Sieve as LDA. Outgoing mail is relayed by our imap-server (with
authentification of course, no open relay).
Most people seem to advice Postfix

able to receive mail with no apparent difficulties, but the log file was disconcerting. A number of

Outlook and TLSv.1

about connection errors, openssl s_client and Thunderbird works fine.

this - I meanwhile disabled TLSv1.2 which made the Outlook users happy.

changing cipher for imap clients
When my client connects, I see this in my log:
dovecot: imap-login: TLSv1 with cipher ECDHE-RSA-AES128-SHA (128/128
bits)
Whereas, when client connects to my postfix server, I see:
Anonymous TLS connection established from * TLSv1 with cipher
ECDHE-RSA-AES256-SHA (256/256 bits)
how can I tell dovecot to use AES256, instead of AES128 ?
is this set by ssl_cipher_list ? Here are my current
