What is a relay server? Do I need one?
A relay server is a mail server (usually SMTP server only) that delivers mail for a 3rd party mail server that is unable to do this on its own due to ISP restrictions, configuration issues and many other factors that may prohibit successful email delivery. Think of a relay server like a package delivery service, you have a package that needs to be sent to a specific location, you cannot do it, so you have this service pick up and take the package, run it through their systems to be placed on a truck for delivery to the final destination. This service is perfect for the following setups or situations…
- Host your own mail server and your ISP blocks port SMTP port 25
- Host your own mail server and your IP address is classified as a residential or dynamic IP address
- Your mail server’s IP address has no reverse DNS configured and your ISP does not allow you to setup reverse DNS
- You run an Exchange (or any other mail server) and require a “Smart Host” or outbound relay server to send your email
- Your mail server’s IP address is listed on 1 ore more realtime blacklists (RBL) services and your ISP will not request delisting or you cannot request delisting
