smtp_address_preference default

Bjoern Franke
Hi,

according to [1] since 2.8 postfix uses ipv6 as default for
smtp_address_preference. But as stated in the doc, it is unsafe as only
IPv6 connectivity is broken, so the safe variant would be any.

Wouldn't it be an alternative that smtp_address_preference could be set
to "ipv6, ipv4" or "ipv4, ipv6" instead of any?


Kind regards
Bjoern

The parameter was introduced in 2.8, the default was changed after
noticing the problem.
Look at the subject line.
