One casualty of the move to new hardware is that the mailing list passwords are invalid.

The way to fix this is to go to Options -> Mail Utilities which is enter the mailing list name and then run the bin/changepw command.

To fix all the passwords, go to Options -> Mail Utilities and enter * for the list names. This will give you all the lists and their passwords. If there are problems, look in the Apache error_log or php.err.

Take the list names and passwords and put them in a file. Then copy ~www/php/mailman/changeallpw to the bin directory version of mailman (e.g. mailman_2/bin) and update the script, changing mailman_N appropriately.

Then run

cat /tmp/pw | bin/changeallpw > /tmp/pw2
sh /tmp/pw2
