Hi all,

We have recently been faced with a few situations where people have been
attempting to subscribe to our double opt-in lists but never receive their
confirmation notices.  I have verified that their subscriptions were
received and that confirmation notices were sent, but they were never
received.  Strangely enough, when I manually add the subscribers they
immediately receive the add notification and the subsequent mailings.

Has anyone else experienced this problem?  I am at a loss as to what is
causing it.

Any help would be greatly appreciated.
