Outgoing SMTP Email Service for Home and Small Business

AuthSMTP provides an outgoing SMTP email server for use on your computer in your business / home office. It will allow you to send emails from most of the major email programs using your own email address or domain name - using AuthSMTP has many advantages compared to using your ISP's SMTP server.

Service Features

Reliable, fast outgoing SMTP email server for sending business or personal emails

Many ISPs offer an SMTP service but your mail can be delayed if their servers become over-loaded or abused - AuthSMTP can solve this problem for you.

Send emails using any Internet connection from all of your email addresses

Some Internet connection providers will only let you send from their own email addresses - with AuthSMTP you can send from your own domain / other email addresses.

Support for all the major email programs such as:

  • Outlook / Outlook Express
  • Thunderbird / Mozilla
  • Apple Mac OSX Mail
  • ...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, full tutorials for almost all major programs and devices

We provide clear and easy to follow setup guides for most major email programs and we frequently add ones for new software /versions.

Outgoing email duplication

AuthSMTP can optionally duplicate all the emails you send to an email address of your choice for backup purposes.

Avoid your emails being blacklisted

Some ISPs outgoing email servers may become blacklisted - we constantly monitor our systems and third party blacklists to help ensure this does not happen.
