I initially installed this server as 0.9.7, and followed the upgrade guide to 0.9.8, making sure to follow the LDAP instructions where applicable.

After upgrading to 0.9.8, I bought iRedAdmin-Pro and installed it.

I'm having problems with mlmmj mailing lists.

I was able to create several mailing lists in iRedAdmin-Pro. However, when I go to my mail user, the checkboxes of the subscribed mailing lists don't accurately reflect the same info as shown in the mailing list subscribers panel.

From my mail user in iRedAdmin-Pro, checking or unchecking mailing lists, and pressing the save button, results in an error in the status area of the browser:  Error: IOError(2, 'No such file or directory')

When I try to send an e-mail to one of the mailing lists which I am listed as subscribed to (in the mailing lists section), I get an immediate bounce, with the error "user unknown".

Despite having added the logging template, I don't see anything in /var/log/mlmmjadmin, instead logs for the admin api are going to the dovecot.log.

When I run:

python /opt/mlmmjadmin/tools/maillist_admin.py subscribers listname@domain.tld

...it returns sane values.

I went through the mlmmj LDAP backend integration to make sure I followed all of the steps, and I didn't find anything that looked incorrect.

Does anyone have any ideas of how I could troubleshoot this?
