I send this out in case others are receiving the same messages.

Over the last couple of days I've received several messages from 'Sandeep
Vansal' whose return e-mail address is indicated as
[log in to unmask] , but trying to reply you get a 'following
address had permanent fatal errors, reason: can't create (user) output
file'.

The e-mail subject lines have been variously:

'Resig-AJ'
'Immuno-404'
'protein assay 4-20-00'

The e-mail always has an attachment indicated which I haven't opened for
obvious reasons.

The message is always:

"Hi! How are you?

I send you this file inorder to have your advice.

See you later.  Thanks."

To my knowledge I don't know a 'Sandeep Vansal' (but at my age, I could
easily have forgotten perhaps a past acquaintance!).

I searched the U. Penn site for this name and found no trace.

It's probably nothing, but you never know.
