Updating Dovecot

PROBLEM
I want to upgrade my Atmail installations version of dovecot.

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.x

CAUSE
Newer versions of Dovecot contain updates to the handling of uidlist files - the issues of which, may lead to difficulties when receiving emails via POP3 or IMAP. It may be a good idea to update your installation. Atmail 6.3.6 uses the 1.2 branch; newer versions of this branch are available for download via: http://www.dovecot.org/download.html

RESOLUTION

1. Download the latest sources from the above link:
   

   wget "http://www.dovecot.org/releases/1.2/dovecot-1.2.17.tar.gz"

2. Untar, then go into the untarred directory:
   

   tar xvfz dovecot-1.2.17.tar.gz
   cd dovecot-1.2.17

3. Stop the Atmail service:
   

   /etc/init.d/atmailserver stop

4. Configure, install:
   

   ./configure --prefix=/usr/local/atmail/mailserver/ --with-mysql --with-ldap --with-docs=no
   make && make install

5. Start the Atmail service:
   

   /etc/init.d/atmailserver restart

6. Congratulations! Now you have the latest Dovecot binaries installed.
