I just wanted to make sure I've read the docs
<https://www.postfix.org/postconf.5.html#check_sasl_access> correctly. I'd
like to restrict a couple of sasl users by IP4/6 (I can't test this on my
sandbox setup), so if I have this in my master.cf:
submission inet n - n - - smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_sender_restrictions=
-o smtpd_milters=
-o { smtpd_client_restrictions=
check_sasl_access hash:/etc/postfix/sasl_access
}
-o { smtpd_recipient_restrictions=
reject_non_fqdn_recipient
reject_unknown_recipient_domain
permit_sasl_authenticated
reject
}
And have the following in my access file:
user1 192.x.x.x PERMIT
user1 2001:x:x:x::x PERMIT
user1 REJECT
(smtpd_sasl_local_domain is blank)
Will that work OK?
