SPAM is a real problem but it even worse worse when sending legitimate email and having some mail servers out there inadvertently flagging it as spam. Even worse than this is when a big company like McAfee is behind this activity. A company which has horrible support and virtually clear processes in place to get unblocked;
I am talking about McAfee and their mxlogic.net spam filtering. This Saas based “cloud based” service filters your mail before your your email server to eliminate junk mail. sounds GREAT right, but if you are an end user and send an email to someone who uses one of your services, beware. Mx Logics mail servers could reject your message without giving you any logical explanation as to what went wrong.
The end user then in frustration calls his ISP.
His ISP looks at the mail server logs and find a similar entry to below
2012-03-06 09:03:52 1S4g0R-0003ac-L5 ** gmancini [at] blahblahblah [dot] com [dot] au R=lookuphost T=remote_smtp: SMTP error from remote mail server after end of data: host maparchitecture.com.au.inbound10.mxlogicmx.net [188.8.131.52]: 554 Denied [CS] [848355f4.0.125264.00-2360.212489.p01c11m096.mxlogic.net] (Mode: normal)
The key is 554 Denied [CS]. Why of course, we all know what that means don’t we,,,,,, NOT.
So, your next step is to contact the world-class McAfee SaaS Email and Web Security customer support team on 1-877-695-6442, who are available 24/7, 365 days a year. Once you get through their support team are instructed to refuse you support unless you are a paying customer. This is obviously not a very well thought out process.
You cant send them an email, forcing you to call them by phone. During the call I strongly suggest you convince them to open a ticket to their accounts department, and request immediate cancellation of this horrible service. This will save you and others hours of wasted time. It will relieve your ISP of having to provide Free McAfee support.
Don’t take my word for it, google “mxlogic.net” and “how to remove listing” to find thousands of articles written by frustrated people just trying to get their user’s email delivered.
