In a normal Kolab setup, the alias domain would work fine.

I assume you are using the TBits multi domain scripts. (error message
from https://github.com/tpokorra/kolab3_tbits_scripts/blob/master/kolab3.1/patches/validateAliasDomainPostfixVirtualFileBug2658.patch#L9)
In the scenario where there is no hard coded domain in the postfix
files but search_base = dc=%2,dc=%1 instead, you need to modify the
aliases manually, otherwise the emails are not delivered properly.
Have a look here:
https://github.com/tpokorra/kolab3_tbits_scripts/blob/master/kolab3.1/patches/validateAliasDomainPostfixVirtualFileBug2658.patch#L35
The file that you need to modify is: /etc/postfix/virtual_alias_maps_manual.cf
If you add one line like this:
@domain1.tld @domain2.tld
You should be fine for all other aliases in that scenario.

Please let me know if you run into problems, I have not put it into
production at TBits yet.
I have created a test here:

I hope this helps,
