Edit /etc/virtusertable

You can make custom changes at the bottom so go down there and add:

user@xxxxxxxxxx error:nouser

(obviously user@xxxxxxxxxx is your problem e-mail address)

And then finally type:

makemap /etc/virtusertable < /etc/virtusertable

To make it live. You won't need to restart sendmail.

basically that'll mean any email to that user will bounce with a "error no
user at this address" something you can't do with default RaQ GUI sadly. ;-(

Subject: [cobalt-users] Spammers forging my email address - Urgent


As of this morning I am getting about 300 emails an hour to a particular
email address.  It seems someone forged my email address and sent out bulk
email to a large list of recipients.  Since some of the addresses or domains
are invalid I am getting bounced email and automated messages from mail
servers (undelivered mail notices and delivery failures).

They are being delivered to (and forged sent from) an email address I use
and cannot block.  I'd like to stop the email from coming into my server,
track down the spammer, or at least filter the email to a junk folder using
procmail until I figure out what to do.  Help!

Also, is there a way to setup a catch-all email account, yet somehow block
specific email addresses?  Right now I have a catch-all email account setup
on the domain b/c there are dozens of email addresses used on the domain
that are routed to the proper mailbox, folder, etc. using procmail.

I am going to research what else I can do, but I figured I would start here.
