the mailman group was deleted on our 2.120 running on ubuntu 18.04. no mail being distributed now

it seems that 1 of our sysadmins inadvertently deleted the group 'mailman'. since then, no mail is being distributed. we re-created the group, but that has not fixed the problem. in order to restore normal operation, perhaps something must be done to this group besides simply creating it. any suggestions appreciated. tnx ams

What about the mailman
user. Is there one and is it's group the
mailman
group.
Beyond that, what does Mailman's bin/check_perms
show?
What happens to mail to Mailman. Is it queued somewhere in one of Mailman's qfiles/*/ queues? What's in Mailman's logs?

Was it created with the same GID? Check that first (run mailman/bin/check_perms).

Group ID always exist because they're just numbers, all the /etc/groups file does is map the ID to a name. I actually suspect that something else is going on... do you see "group mismatch" errors in the mailman logs or in bounce messages?
