Exactly.  I use @googlemail.com because that was the sole domain name in
use when I was issued the address (I've had it since the service was in beta)
and I can't be bothered to switch, but I send mail through smtp.gmail.com.

Really, the big problem here is not that Lisi and I are losing the occasional mail,
or even that we might get involuntarily unsubscribed, it's that someone popping 
in here briefly for help may never see the responses to their message!  We can't 
ask casual visitors to switch email accounts just for the sake of this list.
