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 vmail 8 Apr 13 18:15 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 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.
