Our backup mail server (which I have just re-configured) tries to
contact the primary mail server, and fails. My log shows repeatedly
"connection refused":
May 15 22:21:41 mx2 sm-mta-rx[8674]: q4FIhPij007483: makeconnection
(mail.greenspot.fi. [83.143.217.182]) failed: Connection refused by
mail.greenspot.fi.

stat=Deferred: Connection refused by mail.greenspot.fi.
But yet I can successfully telnet that host:
# telnet mail.greenspot.fi 25
Trying 83.143.217.182...
Connected to mail.greenspot.fi (83.143.217.182).
Escape character is '^]'.
220 mail.greenspot.fi ESMTP Sendmail; Tue, 15 May 2012 22:34:22 +0300
Also, the mailer-daemon *can* send automatic warning messages to
mail.greenspot.fi just fine.
So, the error probably is in my sendmail configuration.
The error appeared as I today reconfigured the backup mail server to use
a "dual sendmail" setup with amavis and greylisting. How could I proceed?
