Securing Postfix – two questions lead the way to Trusted Catalysts

Adam and I (mostly Adam) are working to get postfix configured to run virtual domains in a secure configuration. Along the way, we have come across two challenges and would appreciate some ideas, feedback or insights (links, experience, whatever):

1. Is there any way to setup postfix + sasl to use both CRAM-MD5 and mysql encrypted passwords for secure smtp authentication over TLS? Or is this type of security redundant and unnecessary?

2. Is there a way to set postfix + mysql running virtual mail domains and users so that the users may change their own passwords?

Ideas? Suggestions? Leave a comment or send a note to

Tired of feeling defeated on Friday?

Where the stack of work to get done is bigger than what got finished. You dread next week before the weekend even begins.

It doesn’t have to be this way.
