Brett,

Here's what I get:

# sasldblistusers2
listusers failed

I don't understand why it's even looking for /etc/sasldb2 when my config 
only says to use "shadow".

That said, I used "saslpasswd2 -c -u domain test at domain1.com" and added 
the user's password, then sent a message to my gmail account and it 
worked. "Yay" and "Rats" at the same time; since I'm going to have 
hundreds of users on this box, there's no way I can manage (manually) 
keeping this database in sync with /etc/passwd and /etc/shadow.

How do I get this system to use the /etc/shadow file to check for 
passwords instead of /etc/sasldb2?

Thanks,
Chris
