Hi
In this help page ( https://docs.iredmail.org/manage.iredapd.html ) it shows an example of setting a blacklist by calling a command using python3

python3 wblist_admin.py --account @mydomain.com --list --whitelist

However that leaves an error of module not found (line 8, web.py)

Following the iRed help files to fix this points to installing using python2 ( pip2) and that leaves it broken.
I did the pip-install ... >=0.51 as suggested https://forum.iredmail.org/topic16739-a … 42004.html

It is only when I altered the info from the top article to do a call in python2 that the error disappeared.

python2 wblist_admin.py --account @mydomain.com --list --whitelist

I think there is now a disconnect between the modern iredmail / iredadmin using python3 and the help docs for the issues around import.web.py causing issues.   The help docs are less than 6 months old so likely to be a few people caught in the change over. Possibly the top help file needs a note to try using python2 when adding black lists.

I am using the latest version of iredmail, installed three months ago.
