My Sharepoint Server is configured to use a local SMTP Server (the server's own IIS 6.0 SMTP virtual server). The problem with this is that the message headers of these emails don't receive the reverse DNS information, but I actually have a real mail server running (hMailServer) and I'd rather use that for smtp, or maybe even gmail.
How can I configure my Portal's outgoing email to use an external smtp server? I could set a different Outbound SMTP Server in SCA's Outgoing Email Settings, but there is nowhere to specify the login password for that server.
Or is there a way to make the local SMTP Virtual Server (in IIS6) to use my real mail server for SMTP?
