[SOLVED] Virtual Mailhosting How to reject mail?

[SilverOne]

Hi,

A slightly different-than-usual question regarding the Virtual Mailhosting System with Postfix Guide
I've followed the guide, and I've got a working mail system (and it works beautifully).

The question is: I'm getting a lot of spam to a specific (no longer used) e-mail address. It gets deliverd to the "catchall" @domain address. How do I fit the neatest solution in my mailsystem to block incoming e-mails to that address, without needing to remove the @domain entry in my tables?

Ideally I want the spammers to remove the address from their lists so I want them to get an error like "no such user".
Also I use a lot of addresses that do not forward to a specific mailbox, so I want to keep the catchall.

How can I do this? I have a couple of virtual hosts for others, and at some time in the future I want them to be able to add addresses to a 'block list' themselves, so preferably I'd set it up once, to be administered via MySQL.

Any help greatly appreciated, I've tried searching but no luck so far.

In postfix conf file:-

check_recipient_access hash:/etc/postfix/spam_recipients

in /etc/postfix/spam_recipients

unwanted@example.com REJECT

That'll stop it. You can list any individual unwated addresses in the spam_recipients file.

Remember to run postmap against the spam_recipients file.

Don't kid yourself that they'll ever be removed from spammers' lists - the ratware is not that bright.

Thanks a lot, that's what I needed.

I'll just transform it into a MySQL table (with examples from the guide) and I'm set.

One last question though: if a single e-mail is targetted at multiple addresses (TO/CC/BCC), will one address (that is blacklisted) reject the mail to all addresses (located on the same server)?
This is just theoretical in case one of my users ask me this....

Glad it helped.

It will only reject the email for the specified recipient and not the 'other' recipients.

Roger!

And thanks again.
