Re: Majordomo and spammers

Still sorry All,

Dan replied to my last response, which I also answered.  Both are below:
________________

The more important point of my post, was to modify line 176 of the
"digest" script so you don't have to run an external script
to renumber the files in the $digest_work directory.

As for the problem starting after moving to a new server, have you
carefully examined all the ownerships and permissions of
all the files and directories associated with majordomo AND your MTA?
Is selinux involved?  What about smrsh if you are
running sendmail?

Ok,  The linux is Fedora 8.  Qmail is the mail program.
