main.cf:
# postconf -n inet_protocols
inet_protocols = ipv4, ipv6
# postconf -n inet_interfaces
inet_interfaces = 188.138.4.217, 2001:470:1f0b:bd0::3
That's what I had setup from the start. I'm baffled because I can't override it
in master.cf (referring to the original recipe). By protocol is not enough, I
*have* to set the interface IPv6 address too:
# postconf -Mf smtp-ipv6
smtp-ipv6 unix - - - - - smtp
-o smtp_header_checks=pcre:$config_directory/header_checks_smtp_out
-o inet_protocols=ipv6
-o inet_interfaces=2001:470:1f0b:bd0::3
If I omit the last line, it fails...
