my Sneakemail not getting through

[http://dummy.us.eu.org/robert (Robert)]

A sizeable amount of my sneakemail is not getting through.  I just checked
my destination ("real") e-mail and it's working fine.  But, when I try a
test e-mail to one of my sneakemail addresses, no email gets through.

My account is "robertb".

(Also, strangely, most of the "recent traffic history" seems to be
non-existent and I get an error when trying to access it.  But, I am
worried less about that.)
