Re: the whole greylisting, spam filtering thing

Spammers keep trying, from the same IPs, for days here, so graylisting is useless for us.

On SA and other things that require training, this is a nice story for you. A client received an average of 60 spam items per day on his own inbox alone. He trusted Kasperski, was confident on the accountant's ability to filter manually, and was happy to pay for everybody's waste of time in filtering their own daily dose of junk. This is a company with a cash-flow of 12M per year. One day, the accountant printed a fake bill: both archives and backups were encrypted by a ransomware. The boss paid for it, against the advice of the police, because funding international organised crime is a penal offence here. He obtained the antivirus, but it did not work.

> Hi there, my boss is getting on my nerves that greylisting is basically out of date because of things like outlook.com and mails ending up delayed for ever. So the next logical step would be to deploy a tool like rspamd or spamassasin to examin mail content. These tools need to be trained and if you have a small mailserver with less accounts this could take a while I imagine. So my question is, is there some source that you could use to train these kind of tools (like a database that you could connect to for training conntent ) or is every one here, that uses these tools, lucky enough to have a shit load of users that do the training for your systems? some informations about this would be helpful regards -- Markus Rosjat fon: +49 351 8107223 mail: rosjat@ghweb.de G+H Webservice GbR Gorzolla, Herrmann Königsbrücker Str. 70, 01099 Dresden http://www.ghweb.de fon: +49 351 8107220 fax: +49 351 8107227 Bitte prüfen Sie, ob diese Mail wirklich ausgedruckt werden muss!
