Hello all,
I'm having an issue with Sendmail (8.12.9). I have a few departments on
campus that are able to connect to our SMTP server, however they are unable
to successfully communicate with the daemon. I've tried telnetting from
their mail server to mine. I get connected. I issue a HELO statement, but I
never see a response or a 250 statement. However, it is simply from this
single machine on their network. I'm able to properly communicate from their
backup mail server, which is on the same subnet.
In the logs, I simply see
Jul 29 09:33:59 kari.gtf.gatech.edu sendmail[14878]: SMTP connect from
merlin.dev.gatech.edu [130.207.150.21] (130.207.150.21)
