I need our users to be able to send and receive large messages (max 50MB) to/from remote destinations, but *not* when sending to each other (local mail only)...
Is there a way to do this without a policy server? myhost ~ # postconf -n alias_maps = hash:/etc/mail/aliases, hash:/var/lib/mailman/data/aliases anvil_rate_time_unit = 360s anvil_status_update_time = 3600s bounce_size_limit = 1 broken_sasl_auth_clients = yes config_directory = /etc/postfix delay_warning_time = 15m home_mailbox = .maildir/ message_size_limit = 51200000 mydomain = example.com myhostname = smtp.example.com mynetworks = 127.0.0.0/8 192.168.1.32 parent_domain_matches_subdomains = recipient_delimiter = + relay_domains = relayhost = [post18.example2.com] smtp_fallback_relay = [smtp.example.net] smtpd_hard_error_limit = 3 smtpd_recipient_limit = 100 smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/moved-employees, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_client_access cidr:/etc/postfix/allowed_clients.cidr, check_recipient_access hash:/etc/postfix/x-employees, check_sender_access hash:/etc/postfix/blocked_senders, smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $myhostname smtpd_tls_auth_only = yes smtpd_tls_cert_file = /etc/ssl/wildcard.crt smtpd_tls_key_file = /etc/ssl/wildcard.key smtpd_use_tls = yes transport_maps = hash:/etc/postfix/transport virtual_alias_maps = mysql:/etc/postfix/mysql_vam.cf, hash:/var/lib/mailman/data/virtual-mailman virtual_gid_maps = static:207 virtual_mailbox_base = /var/virtual virtual_mailbox_domains = mysql:/etc/postfix/mysql_vmd.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql_vmm.cf virtual_minimum_uid = 207 virtual_uid_maps = static:207 myhost ~ # Thanks, -- Best regards, Charles
