I have been asked to figure out how to redirect outbound internet mail to a PGP server for encryption, based on criteria such as [PGP] in the subject. Otherwise, route it through the normal SMTP gateway.
I have experience doing conditional routing based on foreign domains/connection documents, but I am at a loss about how to get it done based on content versus destination domain.
None of the mail rule options in the server configuration document seem to apply to my situation.
Anyone got an idea?
Addendum:
I have been able to approximate this with a Location Document (Send directly to internet) plus Connection Document/Account document combination (pointing at the IP address of an outbound SMTP server). However, my management wants me to to continue to look for something that requires less “effort” for the user.
