[Dovecot] xinetd and pop3
by Kurt Krueckeberg 10 Sep '07

10 Sep '07

Is this the best way to get dovecot's pop3 process to run under xinetd? This is what I did after I installed postfix and dovecot. I am using Debian. I am using the dovecot local delivery agent. ---------first the dovecot configuration and version information------------------ dovecot -n output: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%n mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-sql.conf output: driver = mysql connect = host=127.0.0.1 dbname=mailserver user=mailuser password=XXXXXX default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, password FROM view_users WHERE email='%u'; dovecot --version: 1.0.rc15 --------------------------------------- 1. created a file dovecot-pop3 under /etc/xinetd.d with this content: service pop3 { disable = no socket_type = stream protocol = tcp wait = no server = /usr/lib/dovecot/pop3-login user = root } 2. Terminated the dovecot master process #kill -TERM <pid of dovecot> 3. Restarted xinetd #/etc/init.d/xinetd restart 4. telnet'ed to pop3 port. Because I am using the dovecot local delivery agent, postfix needs the dovecot master process and its associated processes already first running; otherwise, postfix will not be able to use the dovecot local delivery agent. #telent localhost pop3 Trying 127.0.0.1...

[Dovecot] multiple emails
by dhottinger＠harrisonburg.k12.va.us 10 Sep '07

10 Sep '07

I have a weird issue where several users are recieving the same email's multiple times. Each email has a different que id, but are exactly the same otherwise. I thought at first this was a new spam, but I have local users doing the same thing. Im not sure where to start looking for the root of this problem. Seems to be pretty widespread across multiple platforms. I currently utilize openldap for user database, sendmail, Dovecot-Imap, and horde webmail. Im not sure where to start digging for this problem, Ive scanned through all my log files and havent found anything. Any guidance would be great. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools

[Dovecot] "pipe() failed: Too many open files"

I am getting random disconnects from my imap session, dificulties to revconnect, very sluggish behaviour when changing between mail folders also frequent and rapidly repititive messages on te client "mailserver x.x.x.x is not a imap4 server" I am running dovecot 1.0.rc2 from ports on OpenBSD 4.0 on a PIII, 500MHz 512MB My set up is very small - a webserver with a single imap account on it for myself and my wife and a pop3 account for a printserver.

[Dovecot] Courier Migration
by Ed W 09 Sep '07

09 Sep '07

Hi Is it legal/sensible to use the following in the conf file # default namespace namespace private { separator = / prefix = inbox = yes } # for backwards compatibility: namespace private { separator = . prefix = INBOX. inbox = yes hidden = yes } The goal would be to migrate away from an Courier server, whilst still supporting clients using their old settings, but going forward they can use the new settings? In particular I always noticed that OE would not set the namespace automatically, so being able to leave it blank would be an advantage (fewer config issues for customers) Grateful if someone could confirm this works ok? Compatibility issues with Thunderbird/OE/Outlook 2003+ in particular? Cheers Ed W
