About blocking specific email address
 

Hello everyone. There is a problem I would like to ask for all your advices.

Situation:
Assume that there is an account called: myacct on linux which has sendmail, spamassassin and procmail.

Now, this sendmail server will receive email from 2 domains:

ABC.com
DEF.com

So, the following 2 emails are valid:

myacct@abc.com
myacct@def.com

Question:
If I don't want to accept any email from myacct@abc.com, but abc.com should be kept. And I also need to receive email from myacct@def.com.

How can I do this?


I have already tried:

Assume that there is a person who send an email to BOTH addresses listed above:

- Procmail: If I blocked the email address of myacct@abc.com, myacct@def.com will also not be able to receive this email. Rules:

:0 BbHh
* ^To:.*myacct\@abc\.com.*
spam

- spamassassin:

blacklist_to myacct@abc.com

myacct@def.com will also not be able to receive this email.


Can any body give some advices to the above situation?

Thank you very much for all your help!

Maybe something like this (to myacct@abc.com and not to myacct@def)?

:0 BbHh
* ^To:.*myacct\@abc\.com.*
* !^To:.*myacct\@def\.com.*
spam
