You are seriously running 2 obsolete Fedora releases as MTAs exposed
to the public net? Setup security patched platforms for public hosts.
ok.
Here is my sendmail.mc file and
let me know if there is a problem?:
<snip!>
DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
Drop 1 below:
DAEMON_OPTIONS(`Family=inet, Port=465, Name=MTA-SSL M=s')dnl
Add 2 below:
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')dnl
So far, the spamming stopped...
You changes are random an do not explain why spammers were/are able
to misuse your Sendmail.
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.
DAEMON_OPTIONS(`Family=inet, Port=465, Name=MTA-SSL M=s')dnl
and
DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')dnl
are equal. There is no functional difference. And offering the
additional daemon on the submission port and enforcing authentication
for that service just adds a function and does not fix anything
previously configured.
In fact using submission on port 587 with STARTTLS is the right thing
How can I do this?
instead of the obsoleted SMTPS on port 465.

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...
