There is no setting per se, nor is there any limit on Subject: length
per se. Mailman does manipulate Subject: headers in the process of
adding the subject_prefix if any. This may result in a subject which
is originally a single line being folded into multiple lines in accord
with RFC 2822, but all Subject: headers sent by Mailman should conform
to the RFC.

Look at the raw message as sent by Mailman. If the Subject: header is
not compliant with RFC 2822, then report that here. Otherwise, look at
the user's MUA (email client).

Note that if this only affects one or a few recipients of the message
but not all recipients, it is almost certainly a user's MUA issue.
