Upgrade to 3.1 breaks existing Mailman lists

The upgrade to ISPConfig 3.1 (Debian 8) wiped out the contents of /var/lib/mailman/data/transport-mailman and /var/lib/mailman/data/virtual-mailman. Adding new mailing lists is working, but the previously created ones do not refresh on their own.

In order to recreate them, it is necessary to rerun:

Code:

sudo /var/lib/mailman/bin/genaliases
sudo postmap /var/lib/mailman/data/transport-mailman
sudo postmap /var/lib/mailman/data/virtual-mailman

And everything is working again.

 

Thanks, I can confirm it, I've had the same problem on my server.

 

Confirmed! Upgrade to 3.1 on Ubuntu also broke my mailman. The fix provided by Teils helped.
