There is one problem: The real message size is only known in the "END-OF-MESSAGE" stage. But not in the "RCPT TO" stage, when smtpd_recipient_restrictions are evaluated. My idea would 'emulate' Postfix' behavior, when the virtual_alias_expansion_limit is exceeded. When virtual_alias_expansion_limit has it's default value (1000) the message to alias1...@example.com, which expands into 1001 recipients, will not be delivered to any of the 1001 recipients. (Do I remember wrong?) Regards, Pascal -- The trapper recommends today: defaced.1106...@localdomain.org
