hermes is a SMTP proxy. What makes it special is that it can be used to stop spam using a combination of the following techniques:
- SMTP banner delay
Most spammers will start sending data as soon as the connection is open, without waiting for the SMTP banner. What we do is delay this banner and if we have data waiting before we print it, we drop the connection.
- Throttling
hermes will process incoming SMTP commands at a slow pace. Most spammers have very little patience, so they will stop sending an email if its taking too long to deliver.
- Greylisting
Greylisting is a process that will delay incoming mails for some minutes before allowing them to be delivered. As most spammers will not resend their messages, you will not receive them. If you want a more technical description, scroll down to read a greylisting description.
- DNSBL
As of hermes 1.2 you can now configure hermes to reject emails coming from ips listed on your favourite DNSBL, using the rbl_domain option.
Main features:
- Multiplatform: hermes runs on Windows, Linux and Solaris
- Transparent: Although clients will connect to hermes, hermes wont display any message of its own or alter in any way the communications with your real mail server, except at the moment of greylisting.
- Efficient: We have gone to great lengths to make hermes as efficient as possible, both for your computer and for the SMTP server that it proxies.
- Configurable: hermes is highly configurable, from greylisting time to logging method and everything in between.
- Extension friendly: We support most SMTP extensions such as SMTP-AUTH and STARTTLS.
- Compatible: You can use hermes in combination with other techniques such as nolisting or Bayesian Filtering either on the client side or on the server side (or both if you prefer). You can also use fakehermes to fake a secondary smtp server and further reduce your spam.
