[Dovecot] POP +OK CR LF Question
by Phil Udel 11 Oct '06

11 Oct '06

HI. I just finished installing a new mail server running CentOS Ver 4. and I am running sendmail with devecot 0.99.11. Everything is working fine except for a customer of mine is using a tool that does pop requests. And his tool is failing waiting on a CR LF in the +OK. I did a small hex dump of my old pop and the dovecot pop and he is right. Docevot POP does not end its +OK with a CR LF. I looked around but I don't see where I can make that change. Can anyone please help. Thanks

[Dovecot] Problems with LDA and vitual mailboxes
by Daniel Frickemeier 11 Oct '06

11 Oct '06

Hello, I try to set up dovecot LDA with virtual domains/mailboxes to use sieve. I use dovecot 1.0_rc7 with sieve dovecot-sieve-20060726 . All datas about the virtual domains and mailboxes are stored in a mysql-database. And without using the LDA delifer agent, everything works fine. But when I try to use LDA (even without sieve), I got a delivery failture. I followed the wiki-howto http://wiki.dovecot.org/LDA to set up LDA support and added /etc/postfix/maser.cf: # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -d ${recipient} /etc/postfix/main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot for postfix. In dovecot.conf I added: auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain login # SQL database passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /etc/dovecot/dovecot-sql.conf } # SQL database userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /etc/dovecot/dovecot-sql.conf } socket listen { master { path = /var/run/dovecot-auth-master # use this for LDA, the dovecot-auth will NOT work mode = 0600 user = virtual #group = mail # Or alternatively mode 0660 + LDA user in this group } client { path = /var/run/dovecot-auth # use this for postfix mode = 0600 user = posfix # postfix user #group = mail # Or alternatively mode 0660 + postfix user in this group } } } protocol lda { log_path = /var/tmp/dovecot-lda.log { And in dovecot-sql # Dataabase driver: mysql, pgsql driver = mysql # Currently supported schemes include PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT. default_pass_scheme = CRYPT #default_pass_scheme = PLAIN-MD5 # Database options connect = host=localhost dbname=$DB user=$USER password=$PASSWD password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 1002 AS uid, 1004 AS gid FROM mailbox WHERE username = '%u' AND active = '1' # eof But when I send a mail to a vitual user, I got the following log entries in mail.log: Oct 11 08:40:38 server postfix/pipe[11673]: D39A5664420: to=<zigulle(a)zigulle.de>, relay=dovecot, delay=0.08, delays=0.06/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure) and in /var/tmp/dovecot-lda.log: deliver(zigulle(a)zigulle.de): Error: userdb(zigulle(a)zigulle.de) didn't return a home directory has anyone here a hint, where the Problem ist? cu Daniel -- TELEKOM-Mitarbeiter, die keine TELEKOM-Aktien kaufen, sollten wegen Verwendung von Insider-Wissen bestraft werden.

[Dovecot] RC8 - Creating maildir
by Luigi Rosa 11 Oct '06

11 Oct '06

I just setup a new mail server with maildir and Dovecot RC 8 I noticed that when I login via POP3 with a username that do not have a maildir yet Dovecot logs this line: Oct 11 11:46:52 gw dovecot: stat(/var/spool/mail/xxxx/) failed: No such file or directory After that Dovecot correctly creates the maildir structure Wouldn't it be better to log a message like "Creating maildir structure for user xxxxxx"? Ciao, luigi -- / +--[Luigi Rosa]-- \ I didn't know it was impossible when I did it.

Hi, I'm using SQL authentication in dovecot, and was wondering if anyone had any ideas as to how I could run an UPDATE statement upon each login, to set time of last login (and other interesting stuff) in the database table. -- Tom

[Dovecot] How Dovecot handles email changed by file operations
by Craig Jackson 10 Oct '06

10 Oct '06

Hi, We have been using Courier-imap for a few years. I am always in the process of reviewing competing software, and hence my interest in Dovecot. Question: If email files are moved between IMAP folders (on the same IMAP server or a different one) or deleted using shell scripts, how does this impact Dovecot's indexes or its method of keeping track of the email? How likely is index or file corruption or race condition? An example, is the centralized removal of mail in all users' Junk folder older than 30 days. We use Maildir format and Dovecot 1.0-RC7 with Mysql. We have about 150 users. Thanks. Craig

So it doesn't look like a memory leak here. The proxies are running great. Thanks, Bill
