dovecot-mysql 1:2.0.15-1ubuntu4 (armhf binary) in ubuntu precise

 Dovecot is a mail server whose major goals are security and extreme
 reliability. It tries very hard to handle all error conditions and verify that
 all data is valid, making it nearly impossible to crash. It should also be
 pretty fast, extensible, and portable.

 This package provides MySQL support for Dovecot.
