I agree with Chris. Although, I don't like the default install
configurations
installing multiple tools that all do the same thing. Perhaps the default
should be to only provide either cyrus-imap or dovecot?
I disagree in this case.
Cyrus and dovecot handle imap for two different scales of systems right
now. Cyrus being a larger more complex system and dovecot being much
more straightforward.
