Novell Filr 1.0


Error in Postfix log such as: "May 16 13:37:55 filrserver postfix/smtp[22290]: connect to[2607:f8b0:4003:c01::1b]:25: Network is unreachable".
No other errors or functionality loss.


This error can be ignore for the most part, sending of notifications should still work, but is being looked into by development.


Caused by either a mis-configuration of Postfix or ipv6 settings.


Reported to Engineering

Additional Information

Since Filr is shipped as a pre-configured appliance, development has been asked to investigate.  Since Filr is pre-configured appliance, it is not recommended to make changes to the server setup itself, unless absolutely needed.

It is believed this happens mainly when sending notifications to GMail users.
