We have just moved our version of Zimbra to 7.1 (FOSS).
Prior to that, both (Open)DKIM and DK are working fine. But after the upgrade to 7.1 both DKIM and DK is not working.
On reason that we have seen is that the value of the following items in postfix main.cf always gets reset to null, every time the zimbra server is restarted or when the machine itself is restarted.
How do we make the value of those permanent? In version 6.0.11, we placed the value of this in by directly editing the main.cf. And the value never gets reset.
milter_default_action = tempfail
milter_protocol = 6
If we put the value like:
the DKIM is working which is using 8891. But the DK is not working which is listening at port 8892.
smtpd_milters = inet:localhost:8891, inet:localhost:8892
Any idea on how to go about this?
Thank you very much in advance.
