Mail problems after following Virtual Users And Domains With Postfix, Courier

Shouldn't but won't hurt to try, Postfix may store it's own cache of the domain. Try putting all the names on the same line:

212.193.49.223 casper.mydomain.com capser mail.mydomain.com

Restart postfix and try again.

hrm...that's weird...if you ping mail.mydomain.com do you get the right IP?

 

yeah i get it from casper.mydomain.com.
ping mail.mydomain.com

btw when the error is
Jan 7 02:14:23 localhost postfix/smtp[23301]: AA87A57200B9: to=<[email protected]>, relay=none, delay=0.06, delays=0.04/0.01/0.01/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=mail.mydomain.com type=A: Host not found)

does type A mean the dns record?

 

the IP you get back is different than the one you specified in your hosts file. although that still doesn't solve the issue here.

Can you post the output of:

cat /etc/resolv.conf

and is mydomain.com the real domain here? is it public?

 

of course not mydomain isn't the real domain of the server nor are those ip numbers. the domain name is something else but its public, server currently is in deployment and security is a bit laxed at the moment.

btw the ip numbers are actually matching i just forgot to put it right

the ip number in the resolv is real though

cat /etc/resolv.conf
search localdomain

nameserver 203.120.90.40

 

Yes it is referring to an A record in DNS. which is weird cause ping finds it no problems. Might be a partially busted zone file, without knowing the real zone it's impossible to test.

Have you made any modifications to /etc/nsswitch.conf?

Try 'dig +short @203.120.90.40 mail.mydomain.com'. That's doing a lookup off the same DNS server you configured the server to use.

PM me the domain if you want me to dig deeper on the DNS issue.

 

no modifications to /etc/nsswitch.conf

/var/named/chroot/var/named/foodspree.com.db

i changed dns here to
mydomain.com. IN NS ns1.mydomain.com.
;mydomain.com. IN NS ns2.mydomain.com.
IN MX 20 smtp.mydomain.com.
IN MX 10 mail.mydomain.com.
ns1 IN A 213.193.49.223 ;primary name server
;ns2 IN A 213.193.49.223 ;secondary name server
casper IN A 213.193.49.223
;serverB IN A 192.168.1.2
smtp IN A 213.193.49.223 ;mail server
mail IN A 213.193.49.223
www IN CNAME casper ;web server
ftp IN CNAME casper ;ftp server

dig +short @203.120.90.40 mail.mydomain.com

does not give anything

what do u need for the real zone file?

 

oh i think i know whats the problem now my transport file

domain transport
foodspree.com smtp:mail.foodspree.com


would this effect the settings? in any case i am gonna turn it off

 

i get this now when i send mail. althought my vmail is still empty

omg your not gonna believe this but it WORKS!! yes!!

 

arggh maybe not i can send mail through my internal accounts in the server to my internal accounts but if i send email through gmail or anything else it doesn't work. although strangely enough no mailer daemon comes back to say the email has bounced

 

Gonna start a new thread for this the nature of the problem has changed significantly
