Hi, using the latest dovecot with pop3/imap. Using mostly outlook 2003 for pop3 and squirrel mail imap. I have a lot of users reporting back that imap is very slow. We average about 300 imap and another 700 pop session at any given time. Here's my config: disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login

With following configuration: userdb static { args = uid=10000 gid=10000 home=/home/vmail/domain.tld/%u/./ mail=maildir:~/maildirs } and accompanying passdb passwd-file consisting of only user and password, for example test:{PLAIN}test: dovecot will access home=/home/vmail/domain.tld/test/home/vmail/domain.tld/test/maildirs instead of home=/home/vmail/domain.tld/test/maildirs dovecot

Hello all, Today I had problems on one of the servers. Dovecot stopped working and I got lots of "Request queue is full" on logs. Aug 14 16:49:45 mailserver03 dovecot: auth(default): ldap(xxx at xxx.com.br): Request queue is full Aug 14 16:49:45 mailserver03 dovecot: auth(default): ldap(xxxxx at xxxx.com.br): Request queue is full Aug 14 16:49:45 mailserver03 dovecot: auth(default):

Hello, I have some strange logs entries in my dovecot_info.log (auth_debug=yes & auth_verbose=ye) : dovecot: Nov 27 00:28:09 Info: auth(default): vpopmail(CLIENT_EMAIL,CLIENT_IP): lookup user= domain=???????? dovecot: Nov 27 00:28:09 Info: auth(default): vpopmail(CLIENT_EMAIL,CLIENT_IP): lookup user=CLIENT_USER domain=CLIENT_DOMAIN dovecot: Nov 27 00:28:09 Info: auth(default):

Hello, dovecot-1.0.3 on Fedora 6 works perfect in general but sometimes the system becomes unresponsive and the log file shows tons of messages like this: ... imap-login: Disconnected: Shutting down: 127.0.0.1, secured ... pop3-login: Disconnected: Shutting down: aa.bb.cc.dd Restarting dovecot helps, but what's behind? What can I do to prevent this? dovecot -n output: #

In our environment home directories are auto-mounted via /home/<user> including on the server provided mail. Within the various mail services though we try to isolate and override with local /mail/home/<user> Works well except that dovecot still wants to cd to the real home triggering a useless and potentially hindering automount when it invokes the imap or pop3 process specified by

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Just to give some more information about this: Apparently some of our POP3 users are saying that when they checked for new mail this morning that all the mail that was saved on the server was downloaded again as unread mail. I followed the guidelines in the wiki [1] with regards to upgrading from 0.99 to 1.0, made sure the .subscriptions and

Hello, With dovecot running already, (accidently) starting another dovecot seems to break the authentication process of the first dovecot. Login will be impossible untill dovecot is restarted. # dovecot Fatal: listen(143) failed: Address already in use ## Wait several seconds. # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot

Dovecot 1.0.3 Deliver is saying this on two specific emails. Other emails to these 2 users are going through fine. Looking at the mail headers the only thing questionable I see is: From: "AMS Publication Division"@ams.org Is this the problem? # 1.0.3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3):

Greetings, i am using here FreeBSD 7.0-RELEASE amd64 with dovecot 1.0.13. Gssapi auth on our dovecot setup did not work for some time, so i wanted to fix it today. I run into an auth failure, where my mutt was not able to login. Also mutt was not able to login, i had a imap/mail2.physik-pool.tu-berlin.de principal in my credentials cache after an try. I can work around with a "ln -s

I have debian lenny configured with postfix 2.5.5 and dovecot 1.0.15 with mysql, every user has a different quota. The problem is that the quota is not ignoring trash folder, how can I solve this problem? And another question, is there a possibility to ignore sent folder?. this is my dovecot.conf smtp:# dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path:

I am trying to tell Dovecot deliver to use $mail_location as the location to store mail for system users. From the docs I've read <http://wiki.dovecot.org/MailLocation> I believe this is possible, but mail to my system users always gets delivered to their /home/<USERNAME> homedirectory. Here's what I've done so far: # Postfix main.cf mailbox_command =

I'm sure I'm missing something obvious :-( Dovecot version 1.1.6, pam authentication via ldap (openldap). basicly, we use: passdb pam userdb passwd which work fine, except for Outlook/OL Express users that are asked for their password whenever they "send/receive"... We've had also "passdb shadow" that somehow "fixed" this but allowed also users with

When stressing dovecot's delivery agent, I sporadically encountered the following assertion failures and the associated errors. I was trickling in ~50 messages per minute to this mailbox via postal.

Hello all, I followed the wiki to configured the expire plugin on dovecot-1.1rc4 and it isn't working.

Hi all, after inserting another sieve-rule, I get the following backtrace on deliver. The mail gets delivered into the Mailbox, but as deliver does not exit with 0, postfix bounces the mail. The additional rule is the same as all others in my .dovecot-sieve: > require ["fileinto", "include"]; > > if header :contains ["From"]

Hello *, I've the following problem with dovecot 1.0.7: /var/log/messages shows | Dec 13 13:48:27 mailbox kernel: possible SYN flooding on port 143.

Hi using dovecot 1.0.10 with pop/imap, using maildir, with 2000+ users mostly using pop but many using imap. Once in a great while I have problems with dovecot pop timing out. If I telnet to port 110 it just takes forever to come up or it doesn't at all, the samething happens on the imap port although 110 is always worst. At 1st when troubleshooting I was not sure what was causing the

Hello all, I'm trying to understand when exactly the variable substitution happens in Dovecot, as I get different results in the LDA and in the POP/IMAP server. Here's my general setup: - Postfix MTA, delivers mail via Dovecot LDA - users list sits in a database - mail directory is stored in the database, but with Dovecot variables inside Delivery works perfectly fine,

Hello, My dovecot works well but I have noticed in logs the following line: Feb 5 09:19:51 lists dovecot: ssl-build-param: Can't create temporary SSL parameters file /var/lib/dovecot/ssl-parameters.dat.tmp: No such file or directory I am not sure when it first appeared but I have not seen it before (and I am using dovecot for more almost 2 years now). $ dovecot -n # 1.0.10:
