Hello,
Can I get a sanity check on this configuration? It's a database setup
of Dovecot 2.2 with Postfix.
I'm having issues and i'd like to know if there's anything glaringly
wrong with my configuration?
With the password hash situation, should I go with SHA512,
SHA512-CRYPT or the SSHA512-CRYPT?
Thanks.
Dave.
