Hell All,

Newbie question here - been running postfix on Mac OS X Server for a
few months now with much happiness and joy.

Having trouble using vacation so I wanted to use virtual_maps and
transport to pipe to an autoresponder script. Since I'm so useless at
UN*X scripting does anyone out here have a handy HOWTO please??

I got the stuff below from searching the list archives and I'd like
to use it but perl and I are still in the "getting to know you" stage.

thanks in advance - adam

> print MAIL <<EOF
> From: MAILER-DAEMON (Automatic reply service)
> To: $sender
> Subject: $user is away from the mail

> Some other text here.
> EOF
> close MAIL || die "$SENDMAIL failed: $!\n";
