specifying "from=<>" in rule

[No Name]

Hi,

I'd like to create a rule where I'll use "From MAILER-DAEMON@* ..."
and the sender address I can see for such e-mails in the log file is from=<>
Can someone advice me how to create a rule to mask this address,
I've tried several options but non of them worked.

Many thanks
Yavor Trapkov
