According to my RaQ550 documentation (this one that I have) It is enough to create such user and disable it. Mail to such users should be bounced even you have catch-all address. Check it on your comp.
Humm, I tried 2 things: created one spammer address and put the bad-addresses in as aliases. Also, tried creating an account with the exact name as the ID, not as an alias. Both accounts were set to SUSPENDED USER.
When I sent the test messages, they were accepted and the mailbox (/home/spool/mail/xxx) has the messages.
Does the suspend user just prevent them from logging on, but the system still accept mail for them? I thought the suggestion sounded great, but it doesn't appear to be working for me. Am I missing the boat on something?
I am on a RAQ3i. THANKS!! Jale
