File system quotas are best. That's for sure. Whether you should be
using Exim's quota enforcement facility og deliverquota (have never
actually used the latter) depends on your setup, what you try to achieve
etc. I'll give some tips regarding the Exim quotas.
Examples are the best way to explain things. My setup matches yours very
much - Exim (surprise!) and Courier IMAP (I do use another BSD however).
User info is stored in PostgreSQL, but this info is dumped to a DB file
which both Courier and Exim use. The DB file is Courier userdb format.
I have three different routers - one to allow custom filters for some
users (Nico's excellent router_home_directory made this possible), one
to do suffix-to-folder-if-exists delivery and one normal delivery to
user's Maildir.
I only post the last router:
courier_maildir:
driver = redirect
domains = +courier_domains
local_part_suffix = -*
local_part_suffix_optional
address_data = ${tr{${lookup{$domain-$local_part}dbmnz{USERDB}{$value}fail}}{|}{ }}
router_home_directory = ${extract{home}{\
${tr{${lookup{$domain-$local_part}dbmnz{USERDB}{$value}fail}}{|}{}}\
}{$value}}
data = ${extract{home}{$address_data}{$value/Maildir/}}
directory_transport = courier_dir
USERDB is a macro that defines where userdb.dat is located.
Now the relevant transport:
courier_dir:
driver = appendfile
maildir_format
maildir_tag = ,S=$message_size
create_file = belowhome
create_directory
quota = ${extract{quota}{$address_data}}
quota_directory = ${extract{home}{$address_data}}
quota_size_regex = ,S=(\d+)
return_path_add
envelope_to_add
message_prefix =
message_suffix =
user = mail
group = mail
As you see, there are three quota-related options. Read the docs for
whay they do.
