Okay, so you know whenever you send an e-mail from your website to either test something or notify you, you sometimes get that signature that says "scanned by blah blah".

Like in Gmail, it says "scanned by blah blah blah".

I was wondering if there was a way to remove that...

Any ideas / suggestions?

The scanned by signature is added by the virus scanner and therefore needs to be disabled by the virus scanner. So if you go into your servers virus scanner configurations you would untick the box for showing the scanned by in the signature. You would also do the same with the virus scanner on your local computer.
