This is what I am trying to understand. I was adding spammers to the
access
database, only to discover that the access database was either ignored or
the access database record added was bogus to begin with.

Ok, so what DAEMONs do I need? So far you said:
? DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
Obsolete: DAEMON_OPTIONS(`Family=inet, Port=465, Name=MTA-SSL M=s')dnl
above identical with below
Obsolete: DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')dnl
No value: DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
Thanks!
I found an old posting you made here:

So, I tried only the two DAEMONs and 'telnet localhost 587' worked!
So far, I see no spamming as of yet...
