Issue with Postfix using "Perfect CentOS 5.3" setup

[varius]

Hi guys,

I just installed a fresh CentOS 5.3 server following the ISPConfig-3 guide to make the "Perfect Server". Everything seemed to work like a charm.

However, I am having issues with sending out mail. Here is the situation:

I have multiple IPs on my server (67.23.188.10-14 usable). I setup my hostname as getzlaf.ghostball.com pointing to IP 67.23.188.14. The problem I am having, is mails being sent out are treated as coming from .10 not .14 like I would like.

Here is an example from GMail headers:

Received: from getzlaf.ghostball.com (ghostball.com [67.23.188.10])
by mx.google.com with ESMTP id 30si10032486yxe.54.2009.11.23.23.54.17;
Mon, 23 Nov 2009 23:54:18 -0800 (PST)

As you can imagine, as it's seeing it sent from .10, it's failing the SPF check.

How can I change the configuration so that Postfix sends out on .14 or uses the hostname, instead of .10 ?

I have tried setting the config option

smtp_bind_address = 63.23.188.14

in my /etc/postfix/main.cf, however then it fails to bind and gives me the following error:

postfix/smtp[16423]: warning: smtp_connect_addr: bind 63.23.188.14: Cannot assign requested address

as well as

amavis[1550]: (01550-20) (!!)WARN: all primary virus scanners failed, considering backups

That makes me think it may be some sort of Postfix/amavisd conflict, perhaps.

I've spent hours on this, Googling and researching and have gotten nowhere ;/

Any help will be greatly appreciated, I am certain it must be something simple!

Thanks

Well I could not solve this, so I just reversed the order of IPs on my server so .14 is first; works fine. Not the proper solution, but I guess it's the only option at this time.
