Hello all,
I am new to running a list and I have a problem regarding the way in which our
campus webmail is managing the messages of my list.
In the "From:" field, instead of the sender name, appears a string like this:

To: [log in to unmask]

How can this be possible?

The closest thing I found in the FAQs is the following,

but before messing with the list header I would like to have your comments.

Thank you for your help,
Cesare Pastorino
