I upgraded to 8.0.2 yesterday and I can't send any e-mails.
First I got the problem when connecting to the OpenDKIM over IPv6 (there was a forum post with a link to the bugtracker somewhere) which I fixed with the temporary fix in the bug notice now this part works.
But the postfix tries to send the email itself. I configured sender based routing like described here: Configure postfix in ZCS v8 as theres no postmap command
That worked perfectly until 8.0.2. I looked at the main.cf and the entries are in the config, so zimbra writes them properly but somehow postfix ignores it and tries to send the mails itself.
Since I can't find anything about this on the forums or the bugtracker I want to ask if someone has the same problem and found a solution about it?
