[SA-exim] Duplicate mails

[Kristopher Austin]

I've also found it very useful to manually test sending an email
manually and make sure your mail server is sending appropriate
responses.

Telnet to mail.yourdomain.com port 25
Helo somehostname
Mail from: your address
Rcpt to: your address
Data
[type an email including headers here]
.

You should get appropriate responses from your server.  Make sure it
looks clean.  We were once getting duplicate email as well.  After I did
this, I discovered that the virus scanner was throwing some error back
to the sending server.  It did not comply with any standard response and
different sending servers handled that differently.

Subject: [SA-exim] Duplicate mails

Hi All

We installed a new Mail Gateway for our Lotus Domino mail server for
spam controlling, using following software,

	exim4 - 4.50-4
	sa-exim - 4.2-2
	spamassassin - 3.0.2-1
	Debian - Sarge

It simply scan all the in-coming mails and forward it to Domino server
to delivery. It's working fine except a small problem.

Problem is, after we place this gateway, we are getting duplicate emails
from certain domains (most of the domains are ok). Specially from
gmail.com and few of our customers. What could be the problem? Or where
should I look in to?

Thanks!

Pradeeper
