First time Installs
-------------------

dovecot-pop3d will not actually start up until the protocols= line in 
/etc/dovecot/dovecot.conf contains one or both of the keywords pop3 (for
POP3 on standard port 110) or pop3s (for POP3 over SSL on standard port 995.)

After making the change, do:

  # invoke-rc.d dovecot restart

to enable pop3d.
