But this would imply that my mail server should be configured to send "HELO mydomain.com" instead of "HELO mail.mydomain.com" where "mail" is the hostname of the mail server. The default value for HELO/EHLO in Postfix is $myhostname, not $mydomain, and I believe most other mail servers send hostname as well. It seems to me the DMARC spec should take into account that, for empty Return-Path's, the HELO/EHLO may be (and probably will be) a fully qualified hostname, not a domain, and adjust the rules for SPF identity alignment matching accordingly.
