Re: BATV mangling email address

[Dane Foster <[e-mail]>]

 At the risk of de-railing the original problem which I’ve answered in
another thread, I’m looking for one of these moderated messages to a list
with headers and all. If you have one, please do reach out and we’ll be
able to sort it out in short order.

Replies off-list please.

Cheers,

Dane
