[RTC List] Tech support question

[Dave Thewlis]

Your basic problem is that your old router had no provision for sending 
authenticated email and apparently there isn't an upgrade to add that 
feature.  My Terastations also want to send their logs via 
non-authenticated email.

Suddenlink like nearly everyone these days requires authentication for 
outbound email through its SMTP server.  It doesn't require SSL or other 
secure outbound, and uses port 25.

My understanding is that Suddenlink blocks port 25 to anywhere but its 
own SMTP server, so if you want to use some other SMTP server it will 
have to use a different port (e.g. Morse Media uses Port 26).
