No. This is wrong. The "mydestination" match list is not subject to parent domain matching, it is a list of literal domains. The relay_domains match list is subject to parent domain matching, and because it defaults to $mydestination, will by default include sub-domains of domains listed in $mydestination. This backwards compatibility should be turned off by all users who don't need it: # Empty relay_domains = # Or relay_domains = <explicit list of domains you want> Best practice is to not use the default value for this parameter. -- Viktor.
