So you just found out that your mail server or fancy new antispam appliance is a full-throttle pipeline for spammers… and you can’t turn it off. Ridiculous? Yes. Impossible? Not at all. You have lots and lots of company.

In case you just fell off the turnip truck, spammers pump junkmail through SMTP open relays so they can waste other peoples’ bandwidth and computer power. Victims end out wondering why their mail servers run so slow and keep crashing.

That’s one of the important reasons network administrators often opt for spam-, virus-, and content-filtering appliances. The devices can insulate fragile email servers from incoming attacks, blocking open relaying attempts without wasting mail server resources.

Simply put, blocking open relay protection is supposed to be an essential function of any antispam appliance. Otherwise, it’s not a serious antispam solution. It’s an advertising tool.

Imagine our surprise when we found advertising tools among the antispam solutions. While some are flippant about their responsibilities, dymeta takes them very, very seriously. That’s what stimulated the 200% No Relay Guarantee.

As a complement to the trimMail Inbox 200% No Relay Guarantee, we’ve assembled all the server-specific information and instructions on open relays we could find at our trimMail Inbox Open Relay Advisory. Look up your mail server or spam firewall to see how it handles open relaying.

Then you can test your setup to make sure you’re not part of the problem.
