OT: replacement for sendmail FEATURE(`redirect')

[Jeff A. Earickson]

Gang,

If any of you use sendmail's REDIRECT feature to bounce "User has moved"
messages back for closed accounts, then you probably know that the feature
is lame beyond words.  It returns a message that is inscrutable to everybody
but mail gurus.  While I've used the feature at my site for a while, most
people hate it because of the returned messages.

I wrote a program mailer "redirect.pl" in perl (attached) and a little
converter program for your aliases file (attached) to convert the old
style REDIRECTs to my program mailer.

I have redirect.pl in production at my site now and people are much
happier.  The perl script also offers a "-f" option to forward the
message on to the new address, as well as return a redirect message
back to the sender.  While the forward option works, it is hit-or-miss
with attachments.

If you want to see how it works in real life, please send email to
trobbins at colby.edu.  This address will not forward messages.

I offer this tool to my fellow MailScanner users in the hope you find it
useful.  Fixes, suggestions, info on use with other mailers (eg Postfix)
would be appreciated.
