I think I might switch my mailservers over to SmarterMail. It has this dandy feature that allows resetting the admin pass, remotely, without authorization.
I am fed up with forgetting the password to my OpenSMTPD+Dovecot root account - at least this will give me a solid experience.

which doesn't seem that smart)*
