I have a dedicated server and have unix/cpanel on it.
I have over 40,000 members of my site and when I email them I get a lot of bounced back emails.
I have told cpanel to filter and emails with certain subject lines.
But it doesn't seem to work.
I am not sure if it is not working because the emails come back to the account@servername
and not back to the webmaster@domainname
But the filter will not work.
I am sure there has to be a way to filter these out but I am at a loss right now.
Any help would be great.
