[Mailman-Users] diacritics in from header with from_is_list set to munge

i just noticed several times now that a bunch of users (most of them
subscribed with their yahoo email address) get bounced off my list
when the senders address contains diacritical marks in their
additional text field describing the name e.g
From: "valérie" <valerie at somesomain.com>
the problem here occurs when setting /munge from/ in from_is_list. the
text between the quotes is merged with the string "via " and then the
name of the list e.g.
From: "valérie via mylist <this at is.my.list>"
but in mailman 2.1.20 this merging breaks presumably because of the
what happens is that the From string in the mailman list header is no
longer a valid email address but two totally mixed up. the then have
the list name split accross both addresses and the domain is not
this obviously violates yahoo's dmarc policy and therefore users start
what can i do?
thanks in advance,
