You probably need to verify that this didn't result in default settings being removed. You have mydestination set, but I don't see the following: relay_domains = $mydestination This is important. The commentary on this setting in my (mostly) default configuration is as follows: # The relay_domains parameter restricts what destinations this system will # relay mail to. See the smtpd_recipient_restrictions description in # postconf(5) for detailed information. # # By default, Postfix relays mail # - from "trusted" clients (IP address matches $mynetworks) to any destination, # - from "untrusted" clients to destinations that match $relay_domains or # subdomains thereof, except addresses with sender-specified routing. # The default relay_domains value is $mydestination. # # In addition to the above, the Postfix SMTP server by default accepts mail # that Postfix is final destination for: # - destinations that match $inet_interfaces or $proxy_interfaces, # - destinations that match $mydestination # - destinations that match $virtual_alias_domains, # - destinations that match $virtual_mailbox_domains. # These destinations do not need to be listed in $relay_domains. # # Specify a list of hosts or domains, /file/name patterns or type:name # lookup tables, separated by commas and/or whitespace. Continue # long lines by starting the next line with whitespace. A file name # is replaced by its contents; a type:name table is matched when a # (parent) domain appears as lookup key. # # NOTE: Postfix will not automatically forward mail for domains that # list this system as their primary or backup MX host. See the # permit_mx_backup restriction description in postconf(5). The commentary says $mydestination is the default, but you are better off specifying it explicitly. -- Louis LeBlanc [EMAIL PROTECTED] Fully Funded Hobbyist, KeySlapper Extrordinaire :) http://www.keyslapper.org ԿԬ Bore, n.: A person who talks when you wish him to listen. -- Ambrose Bierce, "The Devil's Dictionary"
