We're runnning sendmail (8.9.3) and normally all is well and we see the
following listed when we do a ps:
sendmail: accept -bd -q15m -om
For reasons that we're not clear on, every once in a while sendmail is
going into a mode where the machine cannot receive incoming e-mail
messages. When this happens, the ps shows:
sendmail: reject -bd -q15m -om
Can anyone give a pointer to what may be causing this? (Perhaps some
troubleshooting times?) We know that when it happens telnet port 25 is not
being viewed by sendmail. By this I mean if we do a telnet 25, we get a
telnet error message (connection lost, or something like that). Normally we
get a response like:
220 carolina.hops.com ESMTP Sendmail 8.9.3 ..... (a bunch more stuff)
I"m thinking that something has commandeered port 25. Any clues on how to
find out what it might be??
Thanks for any help!
Chris
