If you only allow secure connections, you may need instead of telnet:
openssl s_client -connect your_host_tld:993
or
openssl s_client -connect your_host_tld:143 -starttls imap
a LOGIN username password
a SELECT public/TestFolder1

Hi Aki,
Thanks for your reply. Sorry, hit the reply to and not the reply to all option.
So, even when a folder is a public folder I'm still needing to use the

The public/TestFolder is showing up, the public/TestFolder1 is not.
Thanks.

Hello Aki,
Thank you for your reply.
I've implemented your changes and thanks for the @STRENGTH reminder, I
had forgotten about that one.
I'll check out the acl plugin. Is it required when sharing a public
folder or are public folders usable by all? I know it is for shared
folders.
The TestFolder1 is still not showing up in public not sure why
everything looks good.
My configuration was migrated from 2.0 to 2.1 then 2.2, various ports
along the way.
I was wondering if I could take a look at your dovecot configuration
files and a doveconf -n output?
Thanks.

Hi Aki,
Thanks for your reply. Sorry, hit the reply to and not the reply to all option.
So, even when a folder is a public folder I'm still needing to use the
acl plugin?
The public/TestFolder is showing up, the public/TestFolder1 is not.
Thanks.

I would add @STRENGTH to the end, so it'll get sorted by strengthness.

Configuring virtual all folder:
namespace {
prefix = virtual
location = virtual:/etc/dovecot/virtual:INDEX=%h/virtual
comment = All my messages
special_use = \All
mailbox All {
auto = subscribe
}
}
/etc/dovecot/virtual/All/dovecot-virtual

all

I would recommend you using
mail_plugins = $mail_plugins quota quota_clone
plugin {
quota = count:User quota
quota_clone_dict = proxy::sqlquota
quota_vsizes = true
}
Also,
"Note that the warning is ONLY executed at the exact time when the limit is
being crossed, so when you're testing it you have to do it by crossing the
limit by saving a new mail. If something else besides Dovecot updates quota so
that the limit is crossed, the warning is never executed."

Not sure why it's not showing up, *but*, you could add :INDEXPVT=%h/public to
the folder, to keep per-user indexes separate.

Dovecot does not, as per such, care about your domains. It cares about user
names. If you want to do this kind of thing, please consult ACL plugin.

Some other comments, if you are using SSL, you can drop cram-md5 as auth mech,
it's not storage-safe.
you should use mail_location = maildir:~/maildir:LAYOUT=fs
to avoid your other things in user's home being interprepted as mail
directories.
why are you setting these?
maildir_broken_filename_sizes = yes
maildir_empty_new = yes
maildir_very_dirty_syncs = yes
and in general I see lots of overconfiguring, dovecot defaults are usually
right, and setting various things just for the fun of it, can cause problems.

several misc questions, public folders and sharing, quota, ssl
Hello,
I'm running dovecot 2.29 on a freebsd 10.3 system. I'm wanting to
optimize how the system is running and have a few misc questions.
First ssl, is my cipher list good? I'm trying for pfs and wanting to
ensure these cipherlist is appropriate:
ssl_cipher_list = EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
Next, a new feature that I'm trying for is virtual folders that store
All messages. My understanding of this is that it stores a version of
every received message in one place? I've got the virtual plugin
loaded and have:
mailbox virtual/All {
comment = All my messages
special_use = \All
}
I've got a directory /home/vmail/example.com/username/virtual under
which is an ALL folder both directories are accessible to the vmail
user, yet there's no contents in this folder and it's showing up
nowhere.
Next, quota warnings, are not being sent at all. I set up a testuser
with a quota of 2 mb, then sent a message to that user getting the box
to 95% full, and no message. Took the user overquota with the next
message, still nothing, and a third message did trigger my custom
quota exceeded message and the message was bounced.
I'm wanting to implement public folders. My mailboxes are all
virtual, and they are stored under /home/vmail/example.com/username
and /home/vmail/example.org/username in the maildir format. I've got
one user uid and gid of 999 name of vmail who owns all the mailboxes.
I've separated out public folders storing them under
/home/vmail/public. I've created one mailbox called TestFolder and
new, cur, and tmp directories under it. This is what it looks like:
ls -la /home/vmail/public
total 24
drwx-- 4 vmail vmail 512 Apr 13 18:23 ./
drwx-- 8 vmail vmail 512 Mar 15 10:34 ../
drwxr-xr-x 5 vmail vmail 512 Apr 13 18:16 TestFolder/
drwxr-xr-x 5 vmail vmail 512 Apr 13 18:25 TestFolder1/
-rw--- 1 vmail vmail8 Apr 13 18:15 dovecot-uidvalidity
-r--r--r-- 1 vmail vmail0 Apr 13 18:15 dovecot-uidvalidity.58eff89a
-rw--- 1 vmail vmail 688 Apr 13 18:24 dovecot.list.index.log
ls -la /home/vmail/public/TestFolder
total 28
drwxr-xr-x 5 vmail vmail 512 Apr 13 18:16 ./
drwx-- 4 vmail vmail 512 Apr 13 18:23 ../
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 cur/
-rw-r--r-- 1 vmail vmail 51 Apr 13 18:16 dovecot-uidlist
-rw-r--r-- 1 vmail vmail 304 Apr 13 18:16 dovecot.index.log
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 new/
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 tmp/
ls -la /home/vmail/public/TestFolder1
total 20
drwxr-xr-x 5 vmail vmail 512 Apr 13 18:25 ./
drwx-- 4 vmail vmail 512 Apr 13 18:23 ../
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 cur/
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 new/
drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 tmp/
The public/TestFolder is showing up fine and I can switch to it. The
public/TestFolder1 is not showing up at all so I'm not seeing it and
can't switch to it. Any ideas?
My second question involves public folders and domain sharing. Are
public folders accessible to all users and all domains? I've got two
domains example.com and example.org i'd like to create a folder that
some users in example.com can share with some users in example.org,
not necessarily all users in those domains should be able to see the
folders.
Ideas welcome.
Thanks.
Dave.
