Re: [mlmmj] Permission trouble

Mmm. Yeah. This stuff is a little challenging. It looks like you're
doing well, though. Permissions may be a red herring....

Yeah, good. Seems right.

Should be fine. That's how I run mine so far. I haven't tried
subscriptions using the web interfaces, though.

OK. This is strange. It suggests Mlmmj can't read the subscription file.
After you have subscribed using perl-admin, if you post to the list,
does the message get delivered?

What if you subscribe using perl-admin, and then also subscribe the same
address using list+subscribe@ mail? Do you see two, perhaps slightly
different, entries in the subscribers.d/m file?

Good.

This looks fine.

Well, the group is right. It's only the owner that is www, and the group
permissions are fine.

Well, mlmmj-[un]sub will only be able to use the user of the listdir if
it is run as root, which isn't the case here. Nevertheless, yes, things
should be working.

One final thought... Some OSes don't notice changes to group membership
until after a login. Maybe postfix needs to be stopped and started (and
perhaps just a reload won't work), or even the whole machine rebooted,
to get the OS to notice the change.

Yep. This has already been fixed in version control. Thanks for
mentioning.
