The from_is_list feature does not identify the poster in From: if the poster's From: has no display name.

[Mark Sapiro]

The from_is_list feature creates a new From: header of the form

From: realname via lists_real_name <list_posting_address>

where realname is the display name from the posters From:. If the poster's From: has no display name, this string is null. It should contain at least the local part of the poster's From: address in this case.

It probably should not contain the domain part because this will result in

From: "<email address hidden> via The_list" <email address hidden>

and the presence of two different domain names in the From: header, even if one is in the display name, is said to be an indication of spaminess, so we should make this

From: "user--- via The_list" <email address hidden>
