Besides that, i found that (virtual_mailbox_domains = mysql:/etc/postfix/mysql-domains.cf) unable to "postmap -q wansern.local mysql:/etc/postfix/mysql-domains.cf".

Any ideas ?

Lets conclude if it is not a N/W thing, what does your ping o/p of wansern.local says?

chengli · 01-10-2012, 11:21 PM

Hi Siranjeevi,

PING wansern.local (10.0.0.4) 56(84) bytes of data.
64 bytes from svr01.wansern.local (10.0.0.4): icmp_seq=1 ttl=128 time=0.227 ms

[root@mail ~]# nslookup

wansern.local mail exchanger = 10 mail.wansern.local.

Thanks

Ok,

So your local IP is 10.0.0.7 and your wansern.local and mail.wansern.local IP is 10.0.0.4, ok it should be postfix config, may be you need to disable local delivery parameter in postfix config, wait may be some experts will help you.

chengli · 01-11-2012, 01:01 AM

hi Siranjeevi,

mail.wansern.local= mail server : 10.0.0.7
wansern.local = Dns Server : 10.0.0.4

Thanks

Quote:

best_mx_transport (default: empty)

Where the Postfix SMTP client should deliver mail when it detects a "mail loops back to myself" error condition. This happens when the local MTA is the best SMTP mail exchanger for a destination not listed in $mydestination, $inet_interfaces, $proxy_interfaces, $virtual_alias_domains, or $virtual_mailbox_domains. By default, the Postfix SMTP client returns such mail as undeliverable.

Specify, for example, "best_mx_transport = local" to pass the mail from the Postfix SMTP client to the local(8) delivery agent. You can specify any message delivery "transport" or "transport:nexthop" that is defined in the master.cf file. See the transport(5) manual page for the syntax and meaning of "transport" or "transport:nexthop".

However, this feature is expensive because it ties up a Postfix SMTP client process while the local(8) delivery agent is doing its work. It is more efficient (for Postfix) to list all hosted domains in a table or database.
