[IMGate] Problem Resolving Host PTR

[Kevin Coveney]

I'm seeing internal rejections, apparently do to No PTR record:
NOQUEUE: reject: RCPT from unknown[69.31.119.75]: 554 Client host rejected:

However, 69.31.119.75 does have a PTR record.

Any ideas on why Postfix (2.2.8) is showing unknown on this ??
The Postfix lookup seems to work for IP's outside of this block.

ie:
NOQUEUE: reject: RCPT from 
dslb-084-060-193-010.pools.arcor-ip.net[84.60.193.10]: 550 [EMAIL PROTECTED]:
Recipient address rejected: User unknown in relay recipient table;

Thanks,
Kevin

Header and Body checks can't be whitelisted. It is a limitation of Postfix.

Just to be clear on this...
Is there is no way to Whitelist a server by IP to bypass Header Checks 
or Body Checks.
If thats the case, will I need to remove all header and body checks to 
whitelist the IP of an MTA?

[IMGate] OT: Looking for a good Howto on integrating Antivirus with IMGate

[Kevin Coveney]

If any one has any recommendations on integrating Anti-virus on an 
IMGate or standalone
Postfix box please drop me a link. My old anti-virus server is starting 
to show its age and
I would like to replace it with a Postfix based AV Scanner (current is a 
vendors qmail and
Kaspersky setup). If feel I have a better understanding of the Postfix 
system over the qmail
system and logs. (please no flames)

After Googling around I am only looking for some additional 
tried-and-tested Howtos.
I would really like benefit from others experimenting and testing.
I would be willing (and prefer) to run this on a separate box and under 
FreeBSD.

I am considering ClamAV and/or Kaspersky as the engines - and would be 
willing to hear
other considerations and input on these.

If this is too far off-topic, please feel free to drop me a line 
off-list otherwise on-list is fine
for me.

Thanks all for you input,
Kevin

[IMGate] Restrict a accepting SMTP connections

[Kevin Coveney]

Does anyone know of a setting where Postfix will only accept SMTP 
delivery from a specific set of IPs?

My Configuration is:
[IMGATE(Spam)] -- [POSTFIX(Clam)] -- [Firewall] -- [IMail Server]

I would only like the [POSTFIX(Clam)] to accept mail from [IMGATE(Spam)] 
and not from the
rest of the Internet otherwise spam can bypass the [IMGATE(Spam)] and be 
accepted for delivery.

We have Postfix mynetworks is restricted for relaying but since our 
domains are in the transport of the
[POSTFIX(Clam)] server and it is happy to accept and deliver to [IMail 
Server].

Thanks,
Kevin
