Need help with sendmail error

Post by Alex Tomlins » Thu, 14 Jul 1994 03:56:58



We get the following error about 10 times per hour or more.

   Jul 12 11:31:03 my.machine.edu sendmail[22903]:
   NOQUEUE: SYSERR: putoutmsg (outside.machine.com):
   error on output channel sending "220 ESMTP spoken here":
   Host is unreachable

Details:

  - Each time the message refers to a different host
  - The hosts are reachable via ping.  
  - I inserted newlines for readability (the actual message contains
        no newlines).

Also, these lines appear in /var/spool/mail/qf*:

  MDeferred: Connection reset by peer with some.machine.com
  Mtimeout waiting for input during client MAIL
  MDeferred: Connection reset by peer during client QUIT with foo.bar.edu

Version Info:

  - from `telnet localhost 25`:

220-my.host.edu Sendmail 8.6.9/8.6.5 ready at Tue, 12 Jul 1994 13:52:43 -0500
220 ESMTP spoken here

  - Operating System   SunOS 4.0.3
  - Hardware           Sun 3/80

Any help is appreciated,
Alex Tomlinson
