Perl access to email forwarding

[sverne]

I can use a control panel provided by most web hosting companies to
create email forwarding addresses on my account.

But, I want to accomplish the same thing using a Perl script.

Most sites run sendmail and they do not allow access to the
'virtusertable' since it keeps all the forwards for the whole server.

So, does anyone know of:

1. What email server software I should look for in a web hosting
company that would allow this?

2. A Perl program that can read emails from a catch-all POP3 mailbox
and read the TO: address and then determine where to forward the
email/attachment.

3. Other ways to accomplish this without a dedicated server?

Thanks in advance

Procmail. Use recipes in .procmailrc

use your .forward file on the catch-all POP3 server to launch a Perl
program
see Mail:OP3Client and Mail::Sender

Plenty of POP3 modules on CPAN.

Also plenty of SMTP modules on CPAN.

But... and a big important but, you *cannot* rely on using
the To: address header for your purposes.

I know it might seem obvious that if you have a catch-all account
on a POP3 server, that it should be possible to use the To: field
to distinguish between mail sent to (e-mail address removed) and (e-mail address removed).

However the To: field may not show this information - the
recipient might have been included in a Cc: or Bcc: or
as an alias expanded from a mailing list.

The SMTP protocol does not involve mail headers when mail
transactions occur.
