qmail neverending bounces
I have a problem with my qmail
i use vpopmail, my server supports 3 domains.
The problem is when i send mail to not existing user
qmail creates file, containig that mail address in queue/bounce
with "Sorry, no mailbox by that name..." ans starts neverending bouce, which
i can see in my logs "warning: trouble injecting bounce message..."
How may i solve this problem and make those erornous messages to be returned to sender?
As for now they just stays in that directory and sender is not notified
about not existing mailbox...
