Hey,

uh. So I have this odd thing with Zimbra and dual stack. First off: Both IP6 and 4 are routed, available, allowed in FW.

If I set the zmprov ms `zmhostname` zimbraIPMode ipv6 followed by /opt/zimbra/libexec/zmiptool ipv6 then ipv6 works, ipv4 does not.
If I set the zmprov ms `zmhostname` zimbraIPMode ipv4 followed by /opt/zimbra/libexec/zmiptool ipv4 then ipv4 works, ipv6 does not.
If I set the zmprov ms `zmhostname` zimbraIPMode both followed by /opt/zimbra/libexec/zmiptool both then ipv6 works, ipv4 does not.

Nginx is binding itself to 143 (imap example), but no joy. And yes, I am restarting mailbox after changes. I do see that the nginx-config gets rewritten, including the ipv6only directive in dual-stack mode.

It worked with Zimbra, it broke upgrading to Zextra Zimba 9.

I read through all the materials I could find to no success. Anyone got any pointers?!
