Exactly.
AFAICT, Gmail uses the mail address used for authentication at their
SMTP server as envelope sender when relaying mail to other hosts. So, if
you use foo.bar at example.com[1] as user name  when authenticating to
Gmail's SMTP submission service, Gmail will use foo.bar at example.com as
envelope sender when talking to, for example, the Ubuntu list server.
Which will, if foo.bar at example.com isn't subscribed, reject the mail.

BTW: it seems that the above is true even if you manually use something
else for "mail from" when talking SMTP to Gmail's submission service.

That depends on how Comcast have configured their servers. But my guess
would be, yes, they may likely behave as Gmail, i. e. the envelope
address will be your Comcast address.

Well, it's a sending issue. What you use to read your mail is unrelated.

Yep, using the credentials for the account you're subscribed with when
talking SMTP to Gmail should almost certainly work.

[1] Using example.com to not accidentally use a mail address that might
really exist. When reading, replace "example" by "gmail".
