From: Andreas Henriksson <[EMAIL PROTECTED]> To: exim-users@exim.org Subject: exim behind a NAT gateway and MTA's reverse-tracing the Received-path Hi. I have problem sending mail to some email-addresses (some MTA's), I'll start with describing my situation: I'm connected to the Internet via NAT. I have no access to the servers that have a "real" Internet address, and the chances I can get the admins to change anything is close to zero. I use mutt to send email.. so I need a local MTA to deliver the mail. (This is where I differ from the rest of the users on the network, since regular MUAs have built in SMTP capabilities.) I've tried different configurations without luck... here I'll describe what happens when I configure exim with the eximconfig-tool in debian choosing "Internet site with smarthost". Here is an example of the Received part of the header when I send a mail (foo.dormnet.his.se/10.185.70.45 is my box, and smtp.dormnet.his.se is the smarthost): Received: from smtp.dormnet.his.se [193.10.185.236] by smtp1.home.se with Novonyx SMTP Server $Revision: 2.74 $; Wed, 15 May 2002 16:44:58 +0200 (ECTD) Received: (qmail 51344 invoked by uid 1006); 15 May 2002 14:56:36 -0000 Received: from [EMAIL PROTECTED] by arnold.dormnet.his.se with qmail-scanner-0.96 (. Clean. Processed in 0.210791 secs); 15 May 2002 14:56:36 -0000 Received: from foo.dormnet.his.se (10.185.70.45) by smtp.dormnet.his.se with SMTP; 15 May 2002 14:56:34 -0000 Received: from fatal by foo.dormnet.his.se with local (Exim 3.35 #1 (Debian)) id 17808J-0003Bz-00 for <[EMAIL PROTECTED]>; Wed, 15 May 2002 16:52:03 +0200 Now to the problem.... I've noticed that some servers traces the servers mentioned in Received (for example "telia.com" does), and then they bounce mail when they find MTA-addresses they can't resolve. (my reversed path would be: smtp1.home.se -> arnold.dormnet.his.se -> smtp.dormnet.his.se -> foo.dormnet.his.se, and foo.dormnet.his.se isn't an internet site). ..and they can't resolve foo.dormnet.his.se.. So I'm fucked.. Is there any way I can get exim to use a smarthost and "hide" itself so I get a similar Received path as MUA's under windows produce. (I mean.. MUAs that has built in SMTP capabilities so they can use remote MTAs.) Here is how it looks like when my neighbour sends me a mail: Received: from smtp.dormnet.his.se [193.10.185.236] by smtp2.home.se with Novonyx SMTP Server $Revision: 2.74 $; Wed, 15 May 2002 15:48:32 +0200 (ECTD) Received: (qmail 50995 invoked by uid 1006); 15 May 2002 14:00:10 -0000 Received: from [EMAIL PROTECTED] by arnold.dormnet.his.se with qmail-scanner-0.96 (. Clean. Processed in 0.2167 secs); 15 May 2002 14:00:10 -0000 Received: from wired.dormnet.his.se (HELO wired.home.se) (10.185.70.137) by smtp.dormnet.his.se with SMTP; 15 May 2002 14:00:08 -0000 (His reversed path would be: smtp2.home.se -> arnold.dormnet.his.se -> smtp.dormnet.his.se, all internet sites) maybee not that interesting... but for the record... I've also tried sSMTP which I read was good for "dialup-users". This MTA also applied the local host as the first (or last, depending how you look on it) received element. So it didn't help me.... (and then I would have to find a substitute for fetchmail since sSMTP can't do local deliveries). I hope you understood my problem with running an MTA behind a NAT gateway.
