Upgrading Postfix & Dovecot

First lock the ports so they don't get upgraded by pkg

sudo pkg lock postfix dovecot dovecot-pigeonhole

Upgrade all other packages through pkg

sudo pkg upgrade

Unlock postfix, dovecot and dovecot-pigeonhole

sudo pkg unlock postfix dovecot dovecot-pigeonhole

Upgrade postfix, dovecot and dovecot-pigeonhole via ports

cd /usr/ports/mail/postfix
sudo make deinstall clean reinstall

cd /usr/ports/mail/dovecot
sudo make deinstall clean reinstall

cd /usr/ports/mail/dovecot-pigeonhole
sudo make deinstall clean reinstall

After that, lock ports again to prevent accidental binary upgrades

sudo pkg lock postfix dovecot dovecot-pigeonhole
