Some one sent an email , that looked like it came from an account on my
It was a junk mail, and was sent to 1000's of names.
Most of these didn't exist so they sent replies to my server. Because the
user didn't exist sendmail tried to bounce the messages back.
But because they foreign users don't exist, the messages get returned to me,
double bounce, and delivered to postmaster, whos a/c is filling up, (up to
1000 messages a day)
If I create a new user, with the right user name, then I get all the
messages delivered, but it keeps retrying, sending me warnings that so and
so foreign user doesn't exist, and will continue, (some for five days)
so this gets loads of messages as it retries...
I don't know anyway out, can anybody help me please....
Is there a way I can sent all messages for a user to /dev/null ??
I am running sendmail on solaris 2.6
and I think I'm running 8.9.3 with cyrus imap...
thanks for help
