Nope, but i am really looking forward to finiding out, MailScanner
doesnt really stop anymore. My config remains unchanged since a week or
2 ago, when i upgraded from a perfectly working 4.24-5, now running the
latest stable, an SA 2.63 and something is very wrong, loads of spam
getting through.

I installed SA from source, how would i either de install or install 2.6
or 2.61 over the top. I am starting there, if that oesnt work, how do i
roll back MailScanner to 4.24-5? Will i need to rebuild the machine to
achieve this?
