The first check in our smtpd_recipient_restrictions defers mail for overquota users:
smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/overquota, check_recipient_access hash:/etc/postfix/legacy-domains, . . . The overquota map file just defers messages: x...@domain.edu 460 Mailbox Overquota y...@domain.edu 460 Mailbox Overquota This appears to be working fine, but I heard from a hotmail user today that a multi-recipient message to our domain is being deferred for all recipients. In the postfix logs I see hotmail connecting to us, attempting two addresses that are overquota and then hanging up. My impression was that it should send to all valid recipients and only defer for those that we return a 4xx. Are we incorrectly configured here? Thanks, Rich
