I used to do this for virtual domains...
imapd.conf
configdirectory: /var/lib/imap
partition-default: /u1/cyrus
admins: cyradm
sievedir: /var/lib/imap/sieve
sendmail: /usr/sbin/sendmail
allowplaintext: yes
hashimapspool: false
reject8bit: no
unixhierarchysep: false
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN
tls_cert_file: /usr/share/ssl/certs/cyrus-imapd.pem
tls_key_file: /usr/share/ssl/certs/cyrus-imapd.pem
autocreatequota: 1000000
virtdomains: userid
username_tolower: 1
allowanonymouslogin: no
# Following included just to get rid of stupid log messages
sasl_sql_engine: mysql
sasl_sql_hostnames: localhost
sasl_sql_user: xxxxxx
sasl_sql_passwd: xxxxxx
sasl_sql_database: system
sasl_sql_select: select password from users where user_name = '%u'
saslauthd
# Directory in which to place saslauthd's listening socket, pid file, and so
# on. This directory must already exist.
SOCKETDIR=/var/run/saslauthd
# Mechanism to use when checking passwords. Run "saslauthd -v" to get a
list
# of which mechanism your installation was compiled to use.
MECH=pam
# Additional flags to pass to saslauthd on the command line. See
saslauthd(8)
# for the list of accepted flags.
FLAGS=-r
Then I setup pam to use mysql database...
#%PAM-1.0
#auth required /lib/security/pam_stack.so service=system-auth
#account required /lib/security/pam_stack.so service=system-auth
auth sufficient pam_mysql.so user=xxxxxx passwd=xxxxxx host=localhost
db=system table=users usercolumn=user_email passwdcolumn=user_password
crypt=1 sqllog=N
account required pam_mysql.so user=xxxxxx passwd=xxxxxx host=localhost
db=system table=users usercolumn=user_email passwdcolumn=user_password
crypt=1 sqllog=N
Then I just had exim deliver right to it via lmtp without escaping the @
However, this was 9 months ago, and I since decided to dump cyrus completely
and use courier with SQL backend. I find it much nicer to use, and more
memory efficient on busy machines as exim writes natively to maildir format
and saves all the extra delivery processes / cyrus database overheads.
