Okay, it seems that when I send from the gmail web interface, my msgs
succeed in reaching the list (although they take a long time to
arrive), while messages I send from Seamonkey mail do not, even when
replying to msgs on the list.
Do I then understand...that the problem may be caused by the fact that
my SMTP settings in seamonkey mail are set up to use the
other/nonsubscribed account to access the smtp.gmail.com server?
Maybe I should just use my ISP's smtp server for outgoing mail...but,
then, according to how I understand this problem, would the msgs then
be sent from the addy my ISP gave me (@comcast.net), which I never
use, and which is not subscribed?
I don't recall ever having these issues using POP mail on e-lists,
regardless of what SMTP server I used, and I don't have any such
issues sending msgs to yahoo! groups lists....I wonder if it's just an
IMAP glitch, or a gmail glitch, or what...
Still a little confused...
Perhaps I will just change my SMTP settings to use this acct to access
the gmail smtp server, since the only place I'm having issues is
sending to these lists.
Also, I realize that this might be slightly OT, since it's not really
an Ubuntu issue, but just a list issue, and, in all truth, a mail
issue at my end...So, as such, I appreciate your input.

thanks,
tony
