The first couple of times I set up cyrus-imapd I used Debian packages
which separated mailboxes in the default partition into folders based on
the starting letter of the mailbox; i.e. something like:
/var/spool/cyrus/mail/{[A-Z,a-z,0-9]}/user
Since I have fewer than 50 users and since I found myself frequently
"going to the files" so to speak to definitely determine the presence or
absence of some message a user was concerned about, this hierarchy was
something of a annoyance, so during the last major upgrade I switched
this to:
/srv/imap/{user1,user2,...,userN}
i.e. flattening the folder structure and moving the default partition to
a large non-system disk unaffected by /var volatility.
Now for the life of me I can't figure out what setting in imapd.conf (if
any) facilitated this structure (not the location of the default
partition, but rather not using the [A-Z,a-z,0-9] subfolders.
Last time I left the sieve folders divided by letter; in the next
iteration I'd like to flatten that folder structure to.
Looking at the Arch package post_install script, it pre-creates a ton of
folders:
--------------------------
# all kinds of directories needed for the IMAP spool
for subdir in imap/{,db,log,msg,proc,socket,sieve}
spool/imap/{,stage.}; do
if [ ! -d /var/${subdir} ]; then
mkdir -m 0750 -p "/var/${subdir}"
fi
done
for subdir in imap/{user,quota,sieve} spool/imap; do
for i in a b c d e f g h i j k l m n o p q r s t v u w x y z \
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \
0 1 2 3 4 5 6 7 8 9; do
if [ ! -d /var/${subdir}/${i} ]; then
mkdir -m 0750 -p "/var/${subdir}/${i}"
fi
done
--------------------------
I'm wondering how much or if any of this is really necessary. Will cyrus
autocreate the necessary folders if missing?
