Cctalk subscription disabled

[Tom Hunter]

I didn't receive any cctalk messages for a few days, so I checked my Spam
folder (empty) and then the archive which had several new messages I
haven't seen. I then checked my cctalk membership configuration.
Surprisingly "Mail delivery" was disabled.

Some time ago I received a few emails from the list server about "excessive
bounces" saying that I should simply reply to the email otherwise my
subscription would be disabled. I replied and didn't think too much about
it. This time I got no "excessive bounces" email but my subscription got
disabled.

I got an otherwise reliable @gmail.com email address. Does anyone else here
have problems with this? Is there some way of preventing this from
happening?

Thanks
Tom
