E-MailRelay is a simple SMTP proxy and relay MTA, written in C++, for Linux and Windows. As a proxy all messages can be passed through a user-defined program, such as a spam-filter, which can drop, readdress, or edit messages as they pass through.

User Reviews

  • I Really think this app the perfect app I ever used! => consider having a look at this webiste for Free Gift Cards : www.fregifts.com

  • Mailrelay is the most optimal newsletter distribution system for www.hecmo.com. It's easy to operate and it's constantly updated, effortlessly improving your productivity and performance. The new features are very useful and easy to use - it takes only few minutes to create a stylish A/B and test it. We choose to use Mailrelay because of the great balance of features and the reasonable pricing. Also, we are very satisfied with the response from the support team - it seems that the company has the same values as us, and puts the customer above all else.

  • Great solution if you have a huge amount of SMTP requests from different servers and pcs in your company to the same SMTP server on the web. Providers often limit the ammount of concurrent requests from the same outgoing IP. With this nice tool you can get rid of annoying 421 error messages, Catch them all and relay them every 30 seconds or so and you're fine.

  • Great and helpful software. I will recommend it to my colleagues sysadmins. Developer responded to bug report promptly with solution and bug-fix/solution add. It would be nice to have packages for rmp and deb platform created after bug-fix or feature added but it is not crucial.

  • I love this software! Absolutely amazing that it is free! I use this software to run a local smtp server without authentication for forwarding "Intel Rapid Storage Solution" messages which only supports server without smtp authentication. THANK YOU SO MUCH!!!!!
