Procmail Recipe? 1

[mattjurado]

Looking to specify a list of users to accept mail from at a certain domain, but to not accept any other names at all.

In other words, accept bob@domain.com, carl@domain.com, and alice@domain.com, but reject anyone else from domain.com.

The reason being anyone but these users are fake spam names, and I don't want them to get passed through.

Can this be done via procmail, any other suggestions?

Yes, but it might be even easier to have Postfix do it.

Thank you, I will review that parameter. Didn't even know it existed.

Lgarner, am I missing something (honest question, not being sarcastic)? It appears those parameters looks at the recipient, I'm looking for something to look at the sender.

Its also possible I didn't clearly state my original post, let me try it this way.

Mail server does mail for domain.com. Domain.com has 3 employees, bob, carl, and alice. If any of those 3 send mail to each other, it passes through. However if a spammer forges their domain name and sends an e-mail to bob using bigtitties@domain.com, then it is flagged so it can be sent to our spam location, because bigtitties@domain.com does not exist. I'm not sure if there is a postfix parameter to handle this or a procmail way to get this done. Any help is appreciated.

I may be looking at smtpd_reject_unlisted_sender

You're right, I got the wrong page. check_sender_access is what you want, at
