Reject mails with two different mail addresses in From Header

Hello,

Is there a way to drop mails
which have two different mail addresses in the From header?

This is a common trick of abusers.

For example, mails with a header like:

From: "<John Doe> [email protected] "
<[email protected]>

This is from a real mail (with a password-protected zip
attachment) which obviously is infected.

Can you please provide some amavis/SA setting(s) and/or script
doing that job?

Any other suggestions?

Thanks in advance.

Cheers,

Nick
