Here is what I currently have:
### router/250_exim4-config_lowuid
#################################
.ifndef FIRST_USER_UID
FIRST_USER_UID = 0
.endif
COND_SYSTEM_USER_AND_REMOTE_SUBMITTER = "\
${if and{{! match_ip{$sender_host_address}{:@[]}}\
{<{$local_user_uid}{FIRST_USER_UID}}}\
{1}{0}\
}"
lowuid_aliases:
debug_print = "R: lowuid_aliases for [EMAIL PROTECTED] (UID $local_user_uid)"
check_local_user
driver = redirect
allow_fail
domains = +local_domains
condition = COND_SYSTEM_USER_AND_REMOTE_SUBMITTER
data = "${if exists{/etc/exim4/lowuid-aliases}\
{${lookup{$local_part}lsearch{/etc/exim4/lowuid-aliases}}}\
fail}"
redirect_router = lowuid_target
lowuid_reject:
debug_print = "R: lowuid_reject for [EMAIL PROTECTED] (UID $local_user_uid)"
check_local_user
driver = redirect
allow_fail
domains = +local_domains
condition = COND_SYSTEM_USER_AND_REMOTE_SUBMITTER
data = ":fail: no mail to system accounts"
lowuid_target:
condition = 0
driver = redirect
data = ":fail:"
To enable, one just needs to set FIRST_USER_UID to any non-zero value.
I am not quite happy with this solution as the need for three routers
is somewhat ugly, but I'll commit it this way in case upstream
exim-users does not come up with a more elegant solution.
I'd like to hear your comments.
Greetings
Marc
