how to stop outgoing spam?
Hi,
I have a webmail system (IMP) and using qmail and vpop but we have some users signing up and spamming other ppl with those stupid scams. We have getting complaints back from other ISP but how do I stop this from happenning?
seems like users are signing up, sending a bunch of scams out. and if we ban their ip, delete their account, they just come back and sign up again.
I have no idea how to stop this. is there a outgoing filter?
thanks
edwinx

You could try using SpamAssassin on your outgoing mail. This will only work if the scams have "spammy" heuristics. It can trap most 419-style spams (otherwise known as "my relative died and I need to get 35 million dollars out of the country via your bank account").
Depending on how much outgoing mail you handle, this might be unrealistic as SpamAssassin is CPU intensive.

It's easy to use. Run it in the spamc/spamd configuration, and pass messages to spamc -c on STDIN and check the exit code to see if it's spam or not.
Example .qmail file:
Code:
| bouncesaying "This message is probably spam" except sh -c '/usr/bin/spamc -c'
&user
You can use qmail-qfilter to check mails for spam heuristics before they enter the queue, and block accordingly.

using a service such as spamhaus.org sould free up some system resources if you have a bhusy server.
//edit: nevermind, that wouldn't help your case at all

Outgoing spam.
Somebody spamed my outgoing pop3 mail (hotmail). Everybody in my address book is being sent links, and advertisements such as Viagra. How do I stop this? It's really pissing off my friends, as I'm loading up thier in-box(s).
