[pmg-devel] [PATCH pmg-api] fix #1653: parse ipv6 xfowrard correclty

[Dominik Csapak]

postfix prepends an ipv6 address in the xforward message with 'IPv6:'
we did not remove it and our later checks in who objects fail silently.

we now check if the addr is prefixed with this and remove it to
allow the who objects to work.
