Outgoing SMTP Email Service for Mail Server Administrators
AuthSMTP provides an outgoing SMTP email relay server or 'smart host' for your mail servers with support for all major mail server applications and mail transfer agents. AuthSMTP has many advantages over using your own SMTP server or your ISPs SMTP server such as increased deliverability and less risk of being blacklisted.
High performance SMTP gateway with support for multiple concurrent connections for fast delivery.
Some ISPs offer an SMTP service but your mail can be delayed for hours if they get over-loaded / blocked - with AuthSMTP we attempt immediate delivery.
Correct DNS / Reverse DNS / Feedback Loops
All our servers have valid/ correct DNS and reverse DNS entries. We are already signed up with many of the major ISP feedback loops so you receive notification of complaints / improved deliverability
Support for all the major mail server operating systems and software such as:
- Microsoft Windows Server + Exchange
- Unix / Linux (Sendmail, Postfix, Exim)
- IBM Lotus Domino
- ...and many more.
Automatic virus scanning against all messages
This helps prevent the potentially dangerous / embarrassing situation where someone inadvertently sends or forwards a virus infected email.
Quick and easy to setup guides for most software
