lmtp vs dns?

[centaury]

Hi,
I m running Zimbra 3.0.1 GA on RHEL4

How does lmtp resolve dns?
It looks strange for me...

My initial dns setup was
@ IN SOA localhost. root.localhost. (

IN NS localhost.
MX 10 mail.wwzimbra.com.
mail A 10.1.254.40

and there's an error
Mar 20 17:08:58 localhost postfix/lmtp[28338]: 3F33548D4: to=, relay=none, delay=1, status=bounced (Host o
r domain name not found. Name service error for name=wwzimbra.com type=A: Host found but no data record of requested type)

(1) Why lmtp looking for wwzimbra.com A record of the domain itself?

When I add A record as
@ IN SOA localhost. root.localhost. (

IN NS localhost.
A 10.1.254.10
MX 10 mail.wwzimbra.com.
mail A 10.1.254.40

Error is
Mar 20 17:52:58 localhost postfix/lmtp[26038]: 43F6E24B8C: to=, relay=none, delay=0, status=deferred (connect to wwzimbra.com[10.1.254.10]: Connection refused)

(2) my email server is 10.1.254.40, not 10.1.254.10, Why lmtp send it to 10.1.254.10?

After changed 10.1.254.10 into 10.1.254.40, all deferred email can go through

Mar 20 18:21:53 localhost postfix/lmtp[6665]: 8860524B8E: to=, relay=wwzimbra.com[10.1.254.40], delay=0, status=sent (250 2.1.5 OK)

It does not make sense to change dns like this, as host-10 is default webserver (another host), host-40 is zimbra mail server.

Any idea about this?

Thanks.

Does your DNS setup match this - that works for me on a CentOS 4.2 server. Is your hosts file also set-up correctly?

lmtp sends it to wwzimbra.com because the zimbraMailHost attribute on the destination account is set to wwzimbra.com
