So it seems this is a known issue: https://bugzilla.redhat.com/show_bug.cgi?id=1757157

Zhang , I see even you posted in that thread last October (second post down). The various contributors seem to be making a serious effort to make it work, but they keep discovering more and more obstacles. The bottom line is that it doesn't seem likely that uwsgi, python3, and centos8 are going to be working together in the near future.

Is there any way to install mlmmj without uwsgi? Or another mailing list manager that works with iRedMail?

I'm working on a updated version, stay tuned.
Will update here once finished, and please help test it and let me know if something is not accurate.

Thanks very much for your reply. I will always be happy to help test wherever I can be of assistance.

However, in this case, true to my userid here, I've really just managed to confuse myself, and I now believe that I did not have this issue in the first place.

In a nutshell, I had understood from the installation instructions that mlmmj (not mlmmjadmin) needed to be installed separately if one wanted to use subscribable mailing lists*. I reverted my VM back to an earlier checkpoint and realized that mlmmj was in fact installed during the main install.

However, I ALSO realized that I don't really need subscribable mailing lists anyway, as what I'm trying to reproduce is the behaviour of Exchange's Distribution Lists, which can be subscribable, but in our case aren't. Thus I'm currently looking into Mail Alias Accounts to do this (see my other post re Alias vs Forwards).

Thanks for your help in any case,
Paul

*PS: this might not have been as foolish as it now seems, as there is a sequence of the instruction documents that, if followed carefully, does instruct one to install mlmmj manually. I will write up the sequence I followed in a follow-up post, as it would be good if this erroneous instruction script is corrected / clarified.

PPS: There is another thread on the board at the moment started by someone else who was having issues with Python 3. From the way you worded your response, I get the idea you might have been confusing my issue with his.

So is there a functional difference between creating an account that forwards to a number of existing users (e.g. sales@mycorp.com forwards to alice@mycorp.com, bob@mycorp.com, and carol@mycorp.com) vs using mlmmj with subscription disabled?

Is there a discussion of the pros and cons anywhere?
