This is completely a Postfix issue, dbmail doesn't run an SMTP server.
Check you mail log for postfix/smtpd errors.

This is frustrating…. On SuSE 9.1, I had to do much recompiling and
write a new RPM to get dbmail installed. Actually, Postfix with MySQL
support was the trick, it doesn’t seem to be available as a package
for SuSE 9.x…
But all is installed; MySQL is up, dbmail-adduser works. Postfix is
running, no errors.
But Outlook Express tests and cannot connect to the the SMTP server…
All this is on a local network, trying both by IP and name.
Telnet fails both ports 110 and 25, but OE reports a good POP
connection. I wonder…
No SuSE firewall running, nothing I can see in the way.
Where should I start looking first? I hate when people have such
amorphous questions, but this is all I’ve got….
