In the DATA phase you have access to the message headers, and so your Milter can extract the original alias from the X-Original-To header. If you are using a Milter that doesn't let you do that, you might want to consider using MIMEDefang or MailMunge, both of which allow arbitrary logic (anything you can express in Perl) at each phase. -- Bill Cole _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
