Actually, "ipv4" is not "the default". The default is "all" in builds that
support
IPv6 and don't override DEF_INET_PROTOCOLS via CCARGS:
src/util/sys_defs.h:
/*
* The Postfix 2.9 post-install workaround assumes that the inet_protocols
* default value is "ipv4" when Postfix is compiled without IPv6 support.
*/
#ifndef DEF_INET_PROTOCOLS
#ifdef HAS_IPV6
#define DEF_INET_PROTOCOLS INET_PROTO_NAME_ALL
#else
#define DEF_INET_PROTOCOLS INET_PROTO_NAME_IPV4
#endif
#endif
IIRC, the only thing that changed in 3.x is the default value of
mynetworks_style,
when the compatibility level is set high enough. This has no effect on the
available
protocols.
Whatever pain you're experiencing looks rather self-inflicted.
