MX-Relay Outbound E-Mail Protection

Why outbound email protection?

MX-Relay prevents domain reputation damage and makes every effort to prevent your domain from being blacklisted. All this at a very competitive price.

Protect your reputation

Most companies pay a lot of attention to filtering incoming e-mail, but forget the dangers of outgoing mail. E-mails are often sent directly to the destination and due to network weaknesses, such as unsecured wireless connections or firewalls that allow all kinds of devices to broadcast outbound SMTP, spam or malware can be sent through your network. With all its consequences! You will be placed on a blacklist, making it no longer possible to send e-mails. The administrators must look up the infected computers and remove the unwanted software. You are sometimes busy for days to get rid of the blacklist. In short, it takes a lot of time and money.

A compromised account or compromised user in your network that sends spam can damage the reputation of your IP address and adversely affect email continuity for all users in your network. MX-Relay ensures a clean network and protects your e-mail reputation. Try our service for 30 days for free and experience it for yourself.

Many internet providers block the standard SMTP port, so you cannot send mail. Via MX-Relay you can very easily offer mail on another port. This allows you to continue working.


Also filter all your outgoing mail traffic for spam and viruses. MX-Relay uses the spam filter technology from Barracuda Networks for this. MX-Relay has special, outgoing clusters at multiple locations.


You use a document scanner, but you do not have a mail server to have your scanner sent? MX-Relay gives you this option very easily!
