Yes, although given the available alternatives in the web admin pages
I don't think this is worth the trouble for almost anybody (I
understand that you have a very special situation with a relatively
old Mailman that's working just fine, thank you, for you, but that's
pretty unusual nowadays).

Change the display name to "Sonia Subscriber/lla" (the usual
convention for letters written by a secretary but signed by the boss).

Add a "Reply-To: sonia at her-place.net" header field.
The recommendations above violate the letter but conform to the spirit
of RFC 822 and successor standards.

The above practices should mitigate this issue.
