Yes.

This depends on how you determine the user account. I have two setups
for that.
(1) Local system users with UNIX account, mail spool in home dir:
Director:
|systemuser_maildir:
|# This director matches local user mailboxes. This is needed at least
|# for local root mail which is delivered to admin. Local delivery is
|# not done if SYSTEM_MAILDIR doesn't exist in the user's home dir, so
|# users can control delivery.
| debug_print = "D: systemuser_maildir for $local_part@$domain."
| driver = localuser
| transport = system_maildir_delivery
| require_files = $local_part:+SYSTEM_MAILDIR
SYSTEM_MAILDIR=$home/.mail
Transport:
|system_maildir_delivery:
| debug_print = "T: system_maildir_delivery for $local_part@$domain (SYSTEM_MAILDIR)."
| driver = appendfile
| directory = SYSTEM_MAILDIR
| directory_mode = 0700
| mode = 0600
| maildir_format = yes
| create_directory = yes
| create_file = "belowhome"
| escape_string = ""
| check_string = ""
| prefix = ""
| suffix = ""
| delivery_date_add = yes
| envelope_to_add = yes
| return_path_add = yes
You could authenticate these users against their UNIX accounts via
PAM, but I generally refrain from doing so to prevent a sniffed POP3
session from giving out a shell account, and authenticate local UNIX
users via userdb with a different password.
If users don't have local UNIX accounts, you'd have to use the
smartuser director:
Director:
|domain_maildir:
|# This director matches maildirs in delivery tables.
| debug_print = "D: domain_maildir for $local_part@$domain."
| driver = smartuser
| transport = domain_maildir_delivery
| domains = partial-lsearch;DELITABLEDIR/map
Transport:
|domain_maildir_delivery:
| debug_print = "T: domain_maildir_delivery for $local_part@$domain \
| (VIRTUAL_MAILDIR/${lookup{$domain}partial-lsearch{DELITABLEDIR/map}{$value}}/$local_part)."
| driver = appendfile
| directory = "DOMAIN_MAILDIR/${lc:${lookup{$domain}partial-lsearch{DELITABLEDIR/map}{$value}}}/${lc:$local_part}"
| maildir_format = yes
| user = mail
| group = mail
| directory_mode = 0700
| mode = 0600
| create_directory = yes
| create_file = "belowhome"
| escape_string = ""
| check_string = ""
| prefix = ""
| suffix = ""
| delivery_date_add = yes
| envelope_to_add = yes
| return_path_add = yes
In DELITABLEDIR, text files that I call delivery tables are stored.
There is a map file, too, that maps domains to delivery tables. The
delivery tables are generated from the courier userdb sources with a
shell script:
|#!/bin/bash
|# generates exim deliverytables from the courier userdb
|
|COURIERDIR="/etc/courier"
|USERDBDIR="$COURIERDIR/userdb"
|EXIMDIR="/etc/exim"
|DELITABLEDIR="$EXIMDIR/delitables"
|
|cd $USERDBDIR
|for domain in *; do
| FILE="$DELITABLEDIR/$domain"
| echo > $FILE "# exim delivery table"
| echo >> $FILE "# generated by $0" >> $FILE
| echo >> $FILE -n "# from $USERDBDIR/$domain on "
| date >> $FILE +"%Y-%m-%d %k:%M:%S"
| echo >> $FILE "# do not edit"
| echo >> $FILE
| < $domain sed 's/\([^@]*\).*/\1: \1/' >> $FILE
|done
Maybe it is possible to use the userdb db file directly, but with
Debian, this causes problems with different db libs used by the exim
and courier packages, so I decided to take this additional level of
indirection.
