Description: secure mail server that supports mbox, maildir, dbox and mdbox mailboxes
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 the dovecot main server and its command line utility.
