I hope you can help me with this one.. I know it must be something I am over looking, stupid and simple..
Dedicated server: Fedora core 4 running Cpanel Exim 4.52 with Spamassassin and ClamAV Both are checked in the Exim conf screen in cPanel WHM: Verify the existance of email senders. Use callouts to verify the existance of email senders. According to a thread I read at: http://forums.deftechgroup.com/archive/index.php/t-1034.html "Make sure you UNCHECK "Verify the existance of email senders.". If you are running PHP without phpsuexec, mail sent by scripts and such will be sent as the user "Nobody", which cannot be verified. It will cause you some issues." So I am not sure I want to simply uncheck either of these options. I am not running phpsuexec because a few of the apps on the server do not behave well with it. I no longer have access to the VPS so I can not see what it was set there I just recently moved to this dedicated server, I was on a VPS running Fedora Core 2 and the same versions of cPanel and Exim.. I had none of these issues on the VPS, set the MX to the external servers and I was done. 1domain, 2domain, 3domain & 4domain all have their own external mail servers in-house. 3domain & 4domain use the same mail external mail server each of these 4 domains have NO users set in the mail section of the Cpanel domain WHM, only the MAIN account that is created when the domain is created. each have been set in the DNS zone to point to: domain > MX > 0 > mail.domain.com mail > A > externail.IP mail.domain.com > MX > 0 > externail.IP ; Modified by Web Host Manager ; Zone File for 1domain.com $TTL 14400 @ 86400 IN SOA ns3.NSdomain.com. me.off_server_address.com. ( 2006062900 86400 7200 3600000 86400 ) 1domain.com. 86400 IN NS ns3.NSdomain.com. 1domain.com. 86400 IN NS ns4.NSdomain.com. 1domain.com. 14400 IN A 64.79.202.XXX localhost.1domain.com. 14400 IN A 127.0.0.1 1domain.com. 14400 IN MX 0 mail.1domain.com. mail 14400 IN A 209.42.34.XXX www 14400 IN CNAME 1domain.com. ftp 14400 IN A 64.79.202.138 mail.1domain.com 14400 IN MX 0 209.42.34.XXX OK so here is where I have problems.. Mail sent from off server, passes through and arrives to the external mail servers no problems. Mail generated on the server from forms etc pass through and arrive at the external mail server Mail sent FROM any users from their external mail server TO another user on the server (any domain) is rejected by EXIM. This is a problem not only for my people to contact me, but 3 of these 4 domains have regular communication with other domains/users on the server > > YOUR MESSAGE WAS NOT DELIVERED! > > > > Failed address: [EMAIL PROTECTED] > > > > --- Session Transcript --- > > Parsing Message <C:\MDAEMON\REMOTEQ\pd50000318260.msg> > > From: [EMAIL PROTECTED] > > To: [EMAIL PROTECTED] > > Subject: SS NATURAL > > Message-ID: <[EMAIL PROTECTED]> > > MX-record resolution of my_domain_on_server.COM] in progress (DNS Server: > 198.4.75.100)... > > P=000 D=my_domain_on_server.COM TTL=(168) MX=my_domain_on_server.com] {64.79.202.XXX} > > Attempting MX: P=000 D=my_domain_on_server.COM TTL=(168) MX=my_domain_on_server.com] > {64.79.202.XXX} > > Attempting SMTP connection to [64.79.202.XXX : 25] > > Waiting for socket connection... > > Socket connection established (192.168.0.1 : 3124 -> 64.79.202.XXX : 25) > > Waiting for protocol initiation... > > <-- 220-server.NSdomain.com ESMTP Exim 4.52 #1 Fri, 16 Jun 2006 > 11:30:57 -0400 > > <-- 220-We do not authorize the use of this system to transport > unsolicited, > > <-- 220 and/or bulk e-mail. > > --> EHLO 1domain.com > > <-- 250-server.NSdomain.com Hello 1domain.com [209.42.34XXX] > > <-- 250-SIZE 52428800 > > <-- 250-PIPELINING > > <-- 250-AUTH PLAIN LOGIN > > <-- 250-STARTTLS > > <-- 250 HELP > > --> MAIL From:<[EMAIL PROTECTED]> SIZE=3920462 > > <-- 250 OK > > --> RCPT To:<[EMAIL PROTECTED]> > > <-- 550-Callback setup failed while verifying > <[EMAIL PROTECTED]> > > <-- 550-(result of an earlier callout reused). > > <-- 550-The initial connection, or a HELO or MAIL FROM:<> command was > > <-- 550-rejected.

I belive it is trying to verify USER1 as a LOCAL user because 1domain does exist on the server.. but of course there is no such user here so it bounces the mail. I did several hours of reading and research and found the following repair: >>> You could try replacing it with deny !verify=sender hosts = !63.117.226.XX http://www.exim.org/mail-archives/exim-users/Week-of-Mon-20060612/msg00057.html I edited exim.conf through cPanel Exim editor and that made a bigger problem.. All the mail created locally from forms etc for these 4 domains never left the server, instead they were dropped into the MAIN account for the domains. Since I didn't leave this edit in place for very long I am not sure if it also stopped the mails from off server to these domains to be delivered or not.. but I do know that I had to go in and manually click SAVE for each of the 4 domains after I removed the edit from exim.conf to get mail to go to all of them on their external servers. I hope someone read all this so far and has some help for me.. please be gentle, I am self taught, but not afraid to learn.. thanks Regards, Debbie ^v^ ^o^ //\o/\\ ^o^ ^v^ Webmaster - System Admin [EMAIL PROTECTED] (AOL, CS or AIM NailGdsss - MSN Nailgodess) WWWeb Services, Ronkonkoma, NY 631-981-1273 fax 631-981-7557 http://www.beautytech.com & http://www.beautytech.INFO for Professionals for Consumers -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
