-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, The client is not authenticated therefore the mail is rejected. You should see why the iPad does not make a login attempt. Alternatively you can modify the smtpd_client_restrictions as follows: smtpd_client_restrictions = permit_my_networks, permit_sasl_authenticated, reject_unknown_client and the same email should be accepeted whithout authentication.

All,

I am usually fairly good a diagnosing postfix problems, but this one has me stumped. For some reason, sending mail from Apple products is now not working. I'm not sure what has happened, as all were working sometime in the past when I configured them for the network, but now, they are not. I don't know if this is an IOS change or what. I haven't changed my postfix config in the interim. All of the devices are on the same subnet. The errors I get are:

Jun 4 15:39:39 nirvana postfix/smtpd[18893]: connect from Sydneys-iPad.3111skyline.com[192.168.6.147] Jun 4 15:39:39 nirvana postfix/smtpd[18893]: NOQUEUE: reject: RCPT from Sydneys-iPad.3111skyline.com[192.168.6.147]: 554 5.7.1 : Client host rejected: Access denied; from= to= proto=ESMTP helo=<[192.168.6.147]> Jun 4 15:39:39 nirvana postfix/smtpd[18893]: disconnect from Sydneys-iPad.3111skyline.com[192.168.6.147]

my subnet is 192.168.6.0/24

My postfix config is:

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, drrankin.com myhostname = nirvana.3111skyline.com mynetworks = 127.0.0.0/8 192.168.6.0/24 [::1]/128 [fe80::%eth0]/64 66.76.63.60 mynetworks_style = subnet myorigin = $mydomain

smtpd_client_restrictions = permit_sasl_authenticated, reject_unknown_client smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_client_access hash:/etc/postfix/client_access, reject_unauth_destination (client access includes 3111skyline.com)

broken_sasl_auth_clients = yes

smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $mydomain smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_tls_auth_only = yes smtpd_tls_cert_file = /etc/ssl/certs/dovecot.pem smtpd_tls_key_file = /etc/ssl/private/dovecot.pem

I have tried the normal commenting out of smtpd_client_restrictions, smtpd_recipient_restrictions, smtpd_tls_auth_only = yes (with postfix restart in between) and it makes no difference. It is almost like there is a gremlin that prevents 'Sydneys-iPad' from sending mail. Has anyone else run into this with certain Apple devices lately? If not any suggestions?
