[MM3-users] An issue with the postfix_domains directory creation and the mailman start command.

From Mark's reply of Jul 5, 2024, 3:18 PM:

RE: The mailman aliases command generates the postfix_domains and postfix_lmtp files and calls the configured postmap_command (default /usr/sbin/postmap) to create the .db files. mailman start also generates these files by default.

 1  [mailman3@somehost ~]$ ./venv/bin/mailman start
 2  Starting Mailman's master runner
 3  Generating MTA alias maps
 4  [mailman3@somehost ~]$ sudo ls -l

/opt/mailman3/mm/var/data/postfix_domains 5 ls: cannot access '/opt/mailman3/mm/var/data/postfix_domains': No such file or directory 6 [mailman3@somehost ~]$ ls -dl /opt/mailman3/mm/var/data/ 7 drwxr-xr-x. 2 mailman3 mailman3 6 Jul 5 13:38 /opt/mailman3/mm/var/data/

What should I do about lines 4-7? Thought it might be a permissions issue but it's owned by the correct user. Not sure that i missed any steps, suggestions appreciated.
