Could it be smtpd_sasl_path ignores local (native) lookups even if I specified native lookup for smtp/lmtp client like this in main.cf:
smtp_host_lookup = native, dns lmtp_host_lookup = native, dns This works: smtpd_sasl_path = inet:192.168.6.100:12345 Using a hostname set in /etc/hosts e.g. vlan-director won't: # grep vlan-director /etc/hosts 192.168.6.100 vlan-director smtpd_sasl_path = inet:vlan-director:12345 This results in the following error: Dec 21 01:51:37 mx2 postfix-bulk/smtpd[18434]: fatal: host/service vlan-director/12345 not found: No such file or directory Dec 21 01:51:38 mx2 postfix-bulk/master[18505]: warning: process /usr/libexec/postfix/smtpd pid 18434 exit status 1 Dec 21 01:51:38 mx2 postfix-bulk/master[18505]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling Am I missing another parameter to configure lookup strategy for smtpd_sasl_path?
