Are you trying to say that you want to filter out or reject mails from *@abc.com?
I want the mail server to accept the email from *@abc.com, but I don't want it to be delivered to the user.
1. Some users will be away for long trips, and will be getting their emails through crackberries.
2. A few of them belong to some very heavy mailing lists, that the crackberries can't cope with the volumes.
3. 3 of the users don't want to unsubscribe and later resubscribe to these mailing lists.
Thanks
