Sendmail problem

Tue Aug 26 13:51:34 EDT 2003

So to make sure I'm understanding correctly, when it was connecting to
the localhost, sendmail was working fine, but when connecting to the
real ip address, is when you were having the problems?

When you just tried telnetting, which ip did you do? Try both and make
sure you can connect to port 25 on both. (the reason why I'm asking you
to do this is because sendmail is specifically saying it cannot connect
to the machine..) so let me know what happens in the three below tests:

1. telnet localhost 25
2. telnet 66.202.79.100 25
3. telnet titanium.quinlanco.net 25

also, on that machine when you try to telnet to the machine name, what
IP does it say it's attempting to connect to?

FYI, and I'm sure it's because you have it behind a firewall or using
ipchains/tables, but I tried connecting to port 25 of that ip address
and it refused the connections..

Let me know,
Thanks,
Mark

Mark,

Yes, it's running fine.  NMAP shows the port open and telnetting to it
identifies
it as Sendmail.

One thing I noticed is that before the error, titanium.quinlanco.net was
always
identified by its loopback IP (127.0.0.1) and then when the error
started, it was
identified by its global IP (66.202.79.100).  There are no references to
the
global IP in the earlier maillogs and they contain 0 errors.  However,
after the
first error began, the IP in the maillog for titanium.quinlanco.net was
always
the global IP.

It seems like it might be a DNS issue, but titanium.quinlanco.net has
existed for
months without changes so I don't think this should cause any problems.
Any
ideas?  Thanks a bunch.

-Cliff
