To be honest, I can't follow you. I see that I have inconsistent permissions (but all the same owner and group). I did use a different mail server software in the past, but that's long ago and I can't even remember when I switched to Dovecot. I think it was Courier-IMAP before.
Maildirs for new mailboxes are still created by one of my own scripts so maybe that script creates the maildirs with some wrong permissions. I'll first have to look up what all those funny letters actually mean. They're too rare to remember.
hopefully quick explanation of letters
+-d=directory

My base permissions were : d rwx rwx r-x
most were: : d rwx rws r-x The 's' on the group-triplet means
set-group on files+dirs below this
The exact permissions aren't so important other than to know that permission set on a file. Those perms are in octal (0-7), with octal
- when it creates an internal directory (like .imap/whatever), those it followed the permissions on my original mbox.
- when it creats an internal mbox (like INBOX, Trash, Sent...etc) it may use whatever it's own umask allows. Umasks are often set to system defaults like 022 or 002 on 'friendly systems -- they *remove* a bit from a
you need 3 bits 0111 = 1*4 + 1*2 + 1*1 -- the high bit (multiplied by highest amount, in this case 4, corresponds to the read permission, the 2 corresponds to write permission and the 1 corresponds to execute on files files, or cross-through for directories. So a umask of 022 would filter out the 2nd bit in each permission mask (i.e. the write bit for groups (the middle number) and the write bit for 'other' (the 3rd group) Since I allow groups to write, I have 002 so people in the same group can write.
Windows will use something like 077 on your home directory -- only theuser has any access, by default. the 7's mask out access for any created files.
If the process that runs dovecot runs with a umask different from you, by default it might create differently permissioned files. If you create a directory manually, that also might be different from what you normally see.
In your case 'Trash' had different permissions -- a directory or file that would have been created by dovecot. so it may be running with different default permissions (settable via the usmask), than you.
Hope that helps some rather than confuses more...was a quick summary of stuff.
