email not sending

[Xraywolf]

email not sending, am able to receive.  Get an error message
"sending of message failed. the message could not be sent because the connection to outgoing server smtp.comcast.net timed out"

using mozilla thunderbird, can send mail via comcast page which I rarely ever use.

POP server is mail.comcast.net port 110 as always, any ideas what I could try ?

All other internet activites are ok, can browse and receive but not send.

Are your sending (SMTP) port and SSL/TLS settings correct? See https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email.

Thanks for the reply, not much of that in thunderbird.

I have:

Server type - pop mail server

server name -mail.comcast.net

user name - my user name

security settings - was using none, changed to ssl as per link, no effect

outgoing server - default

authentication method - normal password

Thats about it aside from checking message/storage options.
