Ellie,
Thanks for your feedback. I've just created a new feature request issue
for this: https://github.com/cyrusimap/cyrus-imapd/issues/2372. I don't
have time now to implement it myself, though I'd definitely prefer to
spend time on expanding Cyrus than writing custom scripts if I had the
same need as 4 years ago.
Maybe some new Cyrus user would have time to make it happen, or maybe
I'd find some time later. So the issue is to document the intention and
to have defined some implementation details. Probably, it could have the
"help wanted" tag attached.
Regards,
Anatoli

Something like: autocreate_acl <folder> <user> <acl> (multiple
autocreate_acl entries could be specified)
That's roughly what I'd expect such a feature to look like (without
having thought about it in much depth). It seems like it would be very
useful for admins who don't already have their own provisioning
infrastructure.
Ellie, do you think this is something of low complexity?
In my opinion, any new feature for ACL's is inherently high complexity
-- even if it's just a two line patch -- just because of the amount of
work involved in checking for side effects, error handling, and making
sure the documentation is up to scratch (so that people don't
accidentally configure it wrong and get into trouble).
That said, the code for reading config settings already exists, as does
the code for parsing and applying ACL's. So in theory it should be a
"simple" matter of bolting these bits together in the right place(s).
I'd be happy to review/advise on a pull request along these lines!
Cheers,
ellie

As the default behavior, I agree.
I've just made a couple of tests: remove "anyone p" then add "postman
p" or add postman as "admins: postman" but none of these worked for
plus+addressing (P+A), so the /postman/ user appears to be some
hardcoded way of dealing with LMTP delivery and has nothing in common
with the normal users and operations.
If my assumptions are correct, I guess what Chen (OP) was asking would
be useful, i.e. to be able to define "anyone p" (either as a toggle
aimed at P+A or as a free-form for any user/ACL) for some auto-created
folders along the other auto-configuration features (autocreate_XXX,
x-list, etc.). The idea is to be able to setup most common settings
for new users without any external scripts talking to cyradm or
imtest. In my case the "anyone p" permission is the only thing pending.
Something like: autocreate_acl <folder> <user> <acl> (multiple
autocreate_acl entries could be specified)

So what I'm observing in practice is that the "-a" option is not enough
to deliver plus+addressed mails without the "anyone p" ACL permission in
the folder, which makes me think that the user for "-a" option is not
from the admins group, though it probably should be, right? I.e.
lmtpd -a
should be delivering plus+addressed mails without the "anyone p" ACL
permission?
I think it's good that you have to explicitly set "anyone p", because
otherwise people would be able to send plus-adressed mails to any
mailbox whose name they can guess.
