[TriLUG] Sendmail oddities

Hi Gang,
I think this is related to a buggered MailScanner install, but take a
look and let me know if it sounds like a good hunch:
(FC3 server on relatively new hardware)
- During init, MailScanner tries to start but fails due to
something-or-other. Bad config, maybe; just haven't had time to futz
with it.
- Later in init, sendmail starts with an [ OK ] result.
All seems well. Furthermore:
from somewhere outside, telnet myserver.net 25 results in a normal
conversation with sendmail, from MAIL FROM:<...> through DATA ... all
the way to RSET and QUIT. 200-code success on every command.
HOWEVER...
The message from said entirely normal conversation seems, by all
appearances, to be falling into the bit bucket--it does not end up in
the recipient's mailbox. Yet:
% service sendmail status
sendmail (pid blah blah blah) is running...
% service dovecot status
dovecot (pid blah blah blah) is running...
BUT:
when I go to the sendmail module of webmin on that server, the
start/stop button at the bottom is showing the START option, not the
STOP option, and once I click Start Sendmail in webmin, sendmail begins
actually functioning correctly.
So:
- Why does sendmail indicate itself to be running to the service command
(and the init script), and carry out valid conversations on port 25, if
it's not really running [correctly]?
- Where do those messages go?
- And how come only webmin is alert enough to realize that sendmail is
in fact /not/ running [properly], and is able to correct it? What does
it know that I don't? (obviously lots, but still...)
Thanks a ton,
~Brian
