Mail Filter

[bjblackmore]

Hi,
Has anyone ever created a mail filter? I use php to check my mail online. I have decided to create a mail filter, because I get p**sed off with spam. I was wondering if anyone else had done anything simular? I'm guessing its going to be as simple as using imap_open to open the email, like I already do to read messages. But rather than display the messages, scan the subject/body for certain words (stored in a mysql database) such as porn, mortgage, finance etc and delte the message.
I'm thinking of doing this 2 ways, 1. have a button on the page that displays the message, called filter, and 2. try and get it to run automatically, say once an hour. Is it possible to crontab a php script? If I could tell crontab to run mail_filter.php every hour it would be great.
Anyone have any input/ideas for me?
Cheers
Ben

You're better off installing mail filters upstream. Postfix, for example, can easily be configured to reject SMTP connections from anyone sending mail containing offensive keywords. If you don't have root access to the machine, most Unix systems run everything through procmail to deliver it to local mailboxes, and that provides a user-level tool to screen out spam and porn.

Really, oh right, didn't know that
me reaches for the unix manual
Will have to set mine up, I'm getting p**sed off recieved mails about HRH (hormon replacement) and debt/finance stuff. Whats even more annoying is most of it isn't even available to the UK, just US.
