Maybe a new user?  I didn't know if this was a way to use aliases or be
unidentified or something fancy I'm not aware of.

I approve members to my list and this came in the usual form from
listserv.  Wouldn't that mean it is the address the person used to try to
subscribe or can that be mistaken by listserv?

A  request for  subscription  to the  mylist-L list      has    been
received  from  "Jose    A.  Riestra" <[log in to unmask]>.

You   can,  at   your   discretion,  send   the   following  command   to
[log in to unmask] to add this person to the list:

       ADD mylist-L [log in to unmask] Jose A. Riestra

of most mail  packages are supported,

It arrived in a subscription request from litserv not an error message.
I got an error message when I tried to post to the address.

Any other light you can shed is appreciated.
