having a few issues after a recent virus/malware outbreak last week. I have removed the threat since the outbreak, and verified the public IP has been delisted from all the sites, but now I am still having stuck mail in queue, referencing 451-4.4.0.
Anyone know a quick fix?
1. I have been to http://www.senderbase.org/
and found out my rating is "poor"
-How do I get my rating up in a day?
2. I went to http://www.blacklistalert.org/
and this is the info. that was given; Reverse DNS (PTR) exists and claims to be: mail.imgps.com.
Forward DNS for mail.imgps.com is: 127.0.0.2.
WARNING: Forward-DNS does NOT match Reverse-DNS.
DNS is INCONSISTENT.
-How do I resolve this issue?
This is only occurring on a selective few emails..and I really need to have this resolved ASAP!
