Hi.  I wonder if one of the more experienced listowners can help me
out with a puzzling mail problem.  There is a subscriber on my list whose
e-mail domain is recorded as @helios.uwc.edu.  But most of the mail sent to
her from the list bounces, with an error message like the following:
 
>X-Delivery-Notice:  SMTP MAIL FROM does not correspond to sender.
>Received: from PUCC.PRINCETON.EDU (VMMAIL) by UMDD.UMD.EDU (Mailer R2.08
> PTF008) with BSMTP id 5012; Sat, 13 Feb 93 02:10:10 EST

        I've deleted her twice, most recently today.  But almost as soon as
I deleted her, she resubscribed.  I then tried to write to her to explain
why I deleted her and to ask her to talk to the computer support people at
her institution, but my message to her (sent from a system different from
that of my list) also bounced for similar reasons.
 
        I have two questions.  First, does anyone know whether
helios.uwc.edu does in fact exist (and how could I have found that out for
myself, preferably from my VAX/VMS account, though I do have access to a
VM/CMS account and a UNIX account if need be)?  Also, is there a way to
delete someone so that they can't resubscribe?  I'm not sure I want to do
that, but I'm frankly tired of getting all of this subscriber's bounced mail.
 
        Thanks in advance for your help.
