Kolab 3.4 multi domain patched, email alias lookup fail

[Milan Petrovic]

I was able to have the email delivered to the addr1 at domain6 by changing the
alias line in virtual_alias_maps_manual.cf to:

addr1 at domain6 = addr1 at domain5

If I leave the "=" sign out, the mail log complains that:
fatal: /etc/postfix/virtual_alias_maps_manual.cf, line 1-10: missing '='
after attribute name: "addr1 at domain6 addr1 at domain5"

But, after adding it, the email is received and shown in inbox but the
account from which I've sent the email to addr1 at domain6 get (I'm sending
from gmail) gets an automatic reply saying:

Reporting-MTA: dns; myHostName
X-Postfix-Queue-ID: BB400242398
X-Postfix-Sender: rfc822; myGmail
Arrival-Date: Fri, 25 Nov 2016 12:00:35 +0100 (CET)

Final-Recipient: rfc822; =@myPrimaryKolabDomain.com
Original-Recipient: rfc822;=@ myPrimaryKolabDomain.com
Action: failed
Status: 5.1.1
Diagnostic-Code: X-Postfix; unknown user: "="


How to fix this?
