The data ACL runs *once* per message. The message can have multiple recipients, so which domain do you expect in $domain? Though a "$recipients" variable exists for the DATA acl. If you've different DATA policies for different recipients, you've to single them out at RCPT stage. # part of the RCPT ACL defer condition = $recipients_count Or, if you DATA policies are bound to the domain, you've to check if the domain is known already from a previous recipient, and, if it's the same, accept the message, otherwise defer it: # part of the RCPT ACL defer condition = ${if def:acl_m_domain} condition = ${if !eq{$domain}{$acl_m_domain}} accept set acl_m_domain = $domain Using the $domain as a key for a policy lookup is left as an excercise for the reader :) Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.
