dovecot-dev 1:1.2.9-1ubuntu2 (i386 binary) in ubuntu lucid

 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 contains header files needed to compile plugins for the
 dovecot mail server.
