Dan, it's been best common practice and our policy to block port 25 in both directions on all residential dynamic IP services for a long, long time. There is no work around for this except to smart host though mail.sonic.net.I am adding a email server to my NAS and wanted to host a email server on the NAS it seem to be a technical issue on Sonic side that blocks out going email from the host mail server, Support just stated the block port 25 on their side.
