Subject: Postfix in OpenVZ.
To: Postfix users <postfix-users>

Have recently migrated some servers from linux VServers to OpenVZ.
Postfix fails to start when run inside OpenVZ if the inet_interfaces
config is set to "all". It appears to be because OpenVZ uses bridging
interfaces (venet0 etc), which do not get listed by the SIOCGIFCONF
ioctl. Instead you must use SIOCGIFVLAN.

So should postfix be calling SIOCGIFVLAN as well as SIOCGIFCONF when
listing all interfaces, or should OpenVZ do some "fudging" in the
kernel to make the bridged interfaces behave exactly like real
interfaces?

In other words is this a postfix bug, or an OpenVZ bug? Or is the
"right thing" to list the interface (venet0) in the config file
explicitly? Listing explicitly is bad for migrating applications
between physical hosts, and virtualised environments - there should
not need to be any config changes.

(I am still testing the SMTP SASL auth-fail-map patch, with proxymap
write, will submit it as soon as I have time).
