Default messages stuck in mail queue
when i send myself a message it seems to get stuck and the number of mails in the queue is growing i do not think anything is being delivered i have tried to flush the queue again no mails are delivered. the only thing i have changed was a seemingly unrelated server hostname on another machine.

I changed the hostname from new.computerking.ca to computerking.ca. Could this have an effect on the main mail server shoemasters.com which serves mail for computerking.ca which also has a simple postfix mail server on it.

here are the mx records of the computerking domain they are the same for all my domains

;------------------------------------------------------------------------------

computerking.ca. IN MX 10 shoemasters.com.
computerking.ca. IN MX 20 mx1.canmail.org.
computerking.ca. IN MX 30 mail1.computerking.ca.

mail1.computerking.ca. IN A 68.146.1.51

I am running zimbra version

Release 3.1.4_GA_518.FC3_20060626143230 FC3 FOSS edition

because i think it is last version that works with

Linux shoemasters.com 2.6.12-1.1381_FC3 #1 Fri Oct 21 03:46:55 EDT 2005 i686 i686 i386 GNU/Linux

here are some log outputs please help

Yes, that's quite likely to be the problem. You should have a Split Domain set-up if you have two mailservers in your domain.

I read and reread the split domain setup you mentioned in your last post. I am a bit confused as to what is suggested there. While i was reading the wiki page i decieded to revise my dns for the computerking.ca domain it was a bit messy so i deleted all the uneeded records and now i am recieving mails again whew just in time one was for an upcoming job interview.

I understand the security flaws involved in with the backup mx stuff and am very intrested in setting up the split domain config for a backup server. However I do not quite understand how to do so i must mention that on the secondary server computerking.ca (running FreeBSD) there is no Zimbra only a basic postfix server.

I have the postfix server hostname set to mail1.computerking.ca because this is the name of a backup mx in my dns records for all domains that i host. This seems to work fine as when i send a mail to luck@computerking.ca postfix does not try to accept it but instead sends it on to the shoemasters.com Zimbra server as it should due to the mx records for the computerking.ca domain

I am afraid to begin accepting email for the backup domains as i am already recieving mail for stuff that is the second or third mx record for the domain the spammers are sending to. The split server setup seem to look more secure i hope i can figure it out.
