What is MxGuard Smarthost?

MxGuard Smarthost is an outbound mail relay: route your server's outgoing mail through MxGuard's reputable UK and EU infrastructure so your messages actually arrive, instead of being silently rejected or spam-foldered by the big mailbox providers.

A smarthost is a trusted relay that sends your mail on your behalf. Rather than your own mail server trying to deliver directly to Gmail, Microsoft and Yahoo, it hands each message to MxGuard over an authenticated TLS connection. We relay it out from clean, well-established IP addresses that already have sending reputation — so the receiving side trusts it and delivers to the inbox.

It's a standalone bolt-on you can add to any domain that needs it, billed monthly per account and cancellable at any time. It's also included free during your MxGuard trial.
