ANN: smtp service for UniServe

 [1/5] from: gchiu::compkarori::co::nz at: 8-Mar-2005 21:08


I have written a smtp service for Dockimbel's UniServe. http://www.compkarori.com/vanilla/display/Smtpd.r It uses greylisting as a form of spam protection, and also does some teergrubbing on suspected spam servers - which is any server with no reverse dns, or has a reverse dns suggestive of a dialup, adsl, or cable connection. Suggestions appreciated. -- Graham Chiu http://www.compkarori.com/cerebrus http://www.compkarori.com/rebolml

as far as i can see, it's a local delivery smtp service - is that correct? -- Best regards, Andreas

Hi Andreas, That's correct. And what you do with the incoming mail is up to the reader to implement. I wrote this to solve a problem. A few months ago, some spammers forged my domain for their return address for a mass spamming which resulted in over 10,000 bounces a day. My host took exception to this and pulled the plug on my email. A few days ago, I asked them to point the MX record to my static IP address at home where I have a cable connection. This smtp service deals with all the smtp connections that resulted from that. Over the weekend I was running it, I was getting 2-3000 attempted smtp connections per day. My service is able to recognise most of the bounces, and spam servers, and is even better at it with the new greylisting feature. As a result, with an active spamtrap address enabled, only 20 spam got thru, and all good email made it thru. I have some ideas on extending the greylisting scheme to improve this even further. The incoming mail is currently just saved to the local drive in a mailbox as a unix type mail format. Eventually, I will save it to a database, and then write a pop3 service to retrieve it. I presume that it's not that difficult to add the functionality to send mail outside .. afterall, spamming engines do it .. but I don't have that need at present.

I did.

No, I think I added it just to show how easily it was to configure vanilla. The code came from my article on SOAP http://www.rebolforces.com/zine/rzine-1-02/#sect6. and can be attributed to Johan Forsberg. Thanks for noticing :) -- Graham Chiu http://www.compkarori.com/cerebrus http://www.compkarori.com/rebolml
