Hi,

I have been valiantly attempting to get esmtp mail delivery working for quite some time now!

Firstly, I was using the Perl Mail::Sendmail client to attempt delivery. Thank you Sam for showing it's incorrect smtp dialogue.

Secondly, I was using my hotmail account. Thank you all for a rewarding dialogue about rfc2045, conformance and woe at the fall of fascism in the fortys.

Now I am using Netscape Messenger 4.75 and sendmail-8.11.2-14.

With this I get a DSN with: 546 Routing loop detected -- too many Received: headers.

The logs show a large number of mail messages being generated confirming this behaviour.

I am unsure what may be the cause. On the offchance that it is something trivial, I haven't included any debug here.

Could it somehow be related to my machine being a gateway with two IP addresses? I have a local DNS knowing about the intranet adresses. I do not set any IP address in the esmtpd config and netstat confirms courieresmtp (via couriertcpd) listening on all interfaces.

As an aside, is anyone compiling a list of known Courier friendly and Courier unfriendly smtp clients - this would be most useful!

Thanking you in advance, Alan
