What do you use for an MTA?  I know with postfix you can use some smtp restrictions to solve this problem.

I use Mailscanner and Send mail.  We have a few instances that we are receiving spam from jack at<mailto:jack at> to jack at<mailto:jack at> and it is getting through.  I have not seemed to find and answers as to how to stop this? Anyone got an Idea.  We already have SPF setup which helps but is not fully for this situation.

Thank you.
