I've been using sendmail for quite sometime, and I've run into a problem which I am unable to solve, and I have not been able to find any information online regarding this problem. I have a couple of sendmail servers receiving all the inbound email for a domain. These machines run spamassassin and virsus scanning. Once all the checks are complete the these servers forward all received emails to the courier-mta host. Here is the situation.

When I have an alias that has a destination on the courier-mta host emails are delivered.

When I have an alias that forwards to another domain, and hence is destin for another email server I get the following error:

1. The sendmail machine reports the following trying to send mail to courier:

Mar 7 15:43:42 dc1util01 sendmail[27063]: k27LhXAk027058: to=<[EMAIL PROTECTED]>, delay=00:00:09, xdelay=00:00:08, mailer=smtp, pr i=125743, relay=dc1mail01-int.unpluggedcities.com. [10.64.1.12], dsn=5.0.0, stat=Service unavailable

2.  The courier machine reports:

Mar  7 15:43:33 dc1mail01 courieresmtpd: started,ip=[::ffff:10.64.1.10]
Mar 7 15:43:41 dc1mail01 courieresmtpd: error,relay=::ffff:10.64.1.10,from=<[EMAIL PROTECTED]>,to=<[EMAIL PROTECTED]>: 556 Address u
navailable.
Mar 7 15:43:41 dc1mail01 courieresmtpd: error,relay=::ffff:10.64.1.10,msg="502 ESMTP command error",cmd: DATA

Again, if I use an alias that terminates on the courier machine it works just fine. I was hoping to do email forwarding like sendmail does with the "virtusertable".

Here is a section my of aliases using makealiases -dump

[EMAIL PROTECTED]: [EMAIL PROTECTED]

[EMAIL PROTECTED]: [EMAIL PROTECTED]

[EMAIL PROTECTED]: [EMAIL PROTECTED]
[EMAIL PROTECTED]: [EMAIL PROTECTED]

Any assistance would greatly be appericated...
