TB works fine on other devices. But not picking up incoming mail. Starts by noting connection to mail.comcast.net but then 20 seconds later flashes error "failed to connect to server mail.comcast.net" Not sending either Error msg is n error occurred while sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server 2001:558:fe16:1b::16 (2001:558:fe16:1b::16:587), connect error 10060. This has happened before and usually could be resolved by logging off the router and then reconnecting, but not now. Been fighting this a couple days, so it isn't temporary.
