MailHop Relay

DynDNS® MailHop® Relay allows you to run your own mail server while DynDNS.com filters spam through heuristics and DNS-based blacklists and discards viruses.
We hold and store your mail if your primary mail server goes down, and we can also deliver your mail to an alternate port.

- User lists block mail to non-existent addresses
- Sender whitelisting and blacklisting with pattern matching
- Virus elimination with ClamAV
- DNSBL filtering and discarding
- Backup queuing for unexpected downtime (store and forward)
- Relay mail to any of the following ports: 24, 25, 587, 2525, 10025, 52525
