Re: Spam problems smtp proxy or patch
Hi, currently I am using simscan/spamassasin/tarpit/auth/SSL, also have integrated spamassasin to ldap and set max recipients on 2 but there is always an smart and patience user that start sending spam, they use the webmail or an even a client like outlook/kmal/mail and start to send email one by one. So i was thinking on a solution like some other sites do, to limit the outgoing msg per day but is just that I would like to know how do they do it so i can implement it. regards.
