Postfix error "unix-domain name too long"

[Boindil]

Hi,
when using long domain names plus IPv4 plus IPv6, postfix will stop working. Operating System is CentOS 6.6 with Plesk 12.0.18, latest update. Postfix is version 2.8.14. Upgrading to CentOS 7 is no option because of the downtime by the way.

Oct  3 14:49:48 bighp postfix/master[6835]: fatal: unix-domain name too long: private/plesk-xn--long-domain-name2pd23h.de-IPv4-IPv6

Removing the IPv6 doesn't work either - I had to force correct rebuild by setting the mailserver binding to a single IPv4 and IPv6.

I hope there is a solution to this!
Thanks in advance
