Hello,I submitted a patch for mail/mailman3 more than one year ago [1]. It required updates to multiple ports, which all have been merged, but mail/mailman3 has not. Since the original report, I added an updated patch to upgrade to 3.3.5 and I just finished building 3.3.7 locally.
The current maintainer is AWOL so I'd like to volunteer to take over as port maintainer.
