SMTP-Header-Rewriting for external Mails
Posted on 2003-03-18
we have the Problem, that our Exchange-Server handels Mails by the internal mail-adresses "firstname.lastname@example.org". This is no Problem for internal mail. Mails for external recipients ar relayd by the Windows SMTP-Server to Our ISP. Our ISP does a Header-rewriting for the "mail from" header-field:
email@example.com -> firstname.lastname@example.org
For incoming mail our ISP does it vice versa:
email@example.com -> firstname.lastname@example.org
Is there any chance to do this directly by the Exchange-Server or the SMTP-Service? In the SMTP-Service there is a field "mascarading-domain". But this seems to be only for Error-Messages ...
Thanks for Help
