Re: Help needed setting Procmail as filter

R$+ < @ $=a . > $*
        $#procmail $@ /etc/mail/procmailrc $: $1 < @ procmail > $3
R$+ <@ procmail > $*                            $1 < @ resort.com .> $2

so this sends anything of the form foo(_at_)resort(_dot_)com through procmail
and rewrites it as foo(_at_)procmail(_dot_)  the procmail script reinjects it
and it bypasses the call to procmail and then is rewritten back to
foo(_at_)resort(_dot_)com(_dot_)

/etc/mail/procmailrc:
:0
! -oi -f "$@"
