I would like to configure sendmail to silently drop all mail sent to non-existant users on my system. Currently, the postmaster gets every mail rejection message which looks something like this:
<<< 550-Mailbox unknown. Either there is no mailbox associated with this
<<< 550-name or you do not have authorization to see it.
<<< 550 5.1.1 User unknown
550 5.1.1 <firstname.lastname@example.org>... User unknown
<<< 503 5.5.1 No recipients
I want to use the "discard" internal delivery method to simply drop any mail sent to unknown users. I've searched the web, but can not find what I am looking for.
Any ideas??? pointers:::
