One more question... In the check_message: ACL section, I cannot use the
"domain" filter to specify specific domains.
In that ACL section, how can I specify which domains to do my UTF-8
checking on?
This does not work:
deny domains = !relay_domains
message = UTF-8 not allowed
log_message = UTF-8 not allowed in subject: $rh_subject
condition = ${if match\
{${lc:$rh_subject:}}\
{\N\=\?utf\-8\?\N}\
{yes}{no}}
assuming earlier this was set:
domainlist relay_domains = foo.com : bar.com : baz.com
Error in the logs:
temporarily rejected after DATA: cannot test domains condition in DATA ACL
Basically, I don't want to apply this deny rule on email that is expected
to be sent to another MTA.
