Finally, success!
first I did some tests, it seems:
Most emails I tried to send to debian-user from my titan mail account
got blocked with a warning that I am sending spam. I completed the
captcha and clicked force send.
No response. A couple hours later responses started showing up in the archives. But emails I sent to the list never came back to my inbox.
I tried sending one of my other email accounts an email like:
subject: subscribe
body: which
nwe@mailtu.net
and titan blocked that, informing me I am sending spam!
This confirmed:
it can't be debian-user list fault
I need to find a different email provider.
Here goes. It seems to work.
