Re: smtp authentication

[Aaron Cronkright <aaron@cronkright.com>]

Unfortunatly, I haven't started actually messing around with smtp auth quite 
yet.  I am in the "read all about it" stage.  Sorry I couldn't be of further 
assistance.

I have also read about other mta's and it appears that qmail offers better 
support for smtp auth.

Because I am feeling guilty about this, I am going to yank a suggestion from 
my "Manager's insightful suggestions" jar:  ("Manager's insightful suggestions" 
are nothing more than ambiguous statements that make the manager sound 
technically savvy but are not of much help)

How often does/will your userbase change for this mail server?  If it doesn't 
change very often, you could just leave the sendmail config the way it is and 
create the /etc/sasldb file.  Of course, I am assuming that there is a script 
that will take /etc/passwd and /etc/shadow and turn it into a /etc/sasldb like 
smbpasswd. You could write a simple bash script to create a new user and then 
turn around and create the /etc/sasldb file updated with the new user.

Like I said, not much help and no scalability whatsoever.  But it might get you 
to a point where you can get smtp auth working.
