Try to check settings of your mail server here
http://my-addr.com/full-domain-hostname-dns-info/isp-ip-location-and-geo-city-country/domain_info.php
also you can try to Verify how email going to your server...
It's important because lots of servers check for correct mail sender and user exist

I agree with Desperado, we run all of our mail servers with the DNS client service disabled. It puts a little more strain on our DNS servers, but we get reliable dns queries.]]> Fri, 29 Aug 2008 05:11:33 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6546&PID=12359&title=filter-giving-me-invalid-mx-record#12359 <![CDATA[filter giving me invalid mx record : sepcity, The error can also...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6546&PID=12357&title=filter-giving-me-invalid-mx-record#12357 Author: Desperado

sepcity,

The error can also be caused by a reply-to email being formed improperly ... such as something@mail.yahoo.com, rather than something@yahoo.com.

The clip of the log you included looks, however, like some sort of DNS issue. On the machine that SpamFilter is installed on, try running with the "DNS Client" service stopped and see if the errors reduce. If your ISPs DNS Resolvers fail for a lookup, the DNS Client service will cache that "bad" lookup ... not a good thing for a mail server.

In my setup, I have DNS resolvers that are used just for my mail servers and I clear their cache every 30 minutes. This causes more "outside" lookups but less cached errors. My DNS resolvers DO NOT forward the requests to our primary resolvers but rather, go directly to the authoritative DNS servers for lookups.

I am having the same type of issues. I have my ISP's DNS server configured within SpamFilter. The majority of the messages are resolved without problem however some get quarantined with failure to find MX record. If you look them up, even from the box they failed from, you get a reply no problem.

My first thought was this was a timeout issue so I upped the DNS timeout within the config file but it has had no effect.

Any suggestions? Also, does anyone use an outside commercial company for lookups to get around this kind of problem?

This is caused by either

1 - incorrect DNS server settings in Spamfilter

2 - a DNS server that is not resolving correctly.

Try pointing the DNS servers settings in Spamfilter to a different DNS resolver (such as one of your ISP's servers)

I am getting an invalid MX record when I turn this filter on for I think all the outside domains like yahoo, hotmail and a couple others I noticed

X-SF-HELO-Domain: web81303.mail.mud.yahoo.com
X-SF-Originating-IP: 68.142.199.119
X-Rejection-Reason: 16 - 557 Your domain yahoo.com does not have a valid MX DNS record.
X-SF-SPAM: Y

Could that be something on my DNS server?
