I read the entire ispconfig3_manual.pdf and i dindt found how to update dovecot... For the instalattion i followed this guide: http://www.howtoforge.com/multiserv...se-servers-on-debian-squeeze-with-ispconfig-3 On this link http://www.ispconfig.org/releases/ispconfig-3-0-4-3-released/ There this note: Support for Dovecot 2 on Debian and Ubuntu Linux has been added. Dovecot 2 support on other Linux distributions is experimental. But the line of manual to install dovecot is same of the guide i have used: apt-get -y install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d And the section 4.9.4.3 Updates from manual dont have anything about how to update dovecot.
The dovecot version depends on the linux distribution that you use on your server and not the ispconfig version. The apt line you posted above will automatically install the latest dovecot version that is available for the linux distribution and version that you use, e.g. for debian 6, this is dovecot 1.2. When the next debian version (7) will become available, then this will contain dovecot 2, so as you see, its not related to ispconfig at all, ispconfig supports both dovecot versions out of the box.
