in reply to Net::SMTP and resolving an alias

Outlook simply looks up previously entered email addresses, and it can pick the wrong on. It has no knowledge of what an email, smtp, server may know.

No, I don't think you can make Perl query the smtp server for email addresses; that would be a security risk.
