$acl_c0 – $acl_c19
Values can be placed in these variables by the set modifier in an
ACL. The values persist throughout the lifetime of an SMTP connection.
They can be used to pass information between ACLs and different
invocations of the same ACL. When a message is received, the values of
these variables are saved with the message, and can be accessed by
filters, routers, and transports during subsequent delivery.
$acl_m0 – $acl_m19
Values can be placed in these variables by the set modifier in an
ACL. They retain their values while a message is being received, but are
reset afterwards. They are also reset by MAIL, RSET, EHLO, HELO, and
after starting a TLS session. When a message is received, the values of
these variables are saved with the message, and can be accessed by
filters, routers, and transports during subsequent delivery.
Using add_header in a router with the content of the acl_m* variable
will split the message into separate instances per unique header value.
