My two cents, Configure your postfix/sendmail to masquerade entire envelope and sender, Exchange sometimes (at least on Office365) doesn't allow sender differ from authenticated user or someone doesn't exists in his database.
If im correct on postfix search for generic tables and sendmail on /etc/sendmail.mc (or .cf always forgot) for MASQUERADE options and generic maps. If you use Debian/Ubuntu just install ssmtp and put your authentication/relay configuration on /etc/ssmtp -----Mensagem original----- De: [email protected] [mailto:[email protected]] Em nome de Chris Herrmann Enviada em: quarta-feira, 7 de novembro de 2012 19:12 Para: [email protected] Assunto: [rt-users] Exchange & rt Setup a contact for your desired queue email address - for example: [email protected] And the contact delivers to: [email protected] Similarly configure a comment address: [email protected] --> [email protected] Set the primary domain as the primary address eg [email protected] Configure the queues to the rtserver.mydomain.com addresses.
