Hi Uwe,
I also have and use NS 6.8 with SOGo in this configuration (multiple email domains placed in DMZ).
Unfortunately, I understand that this approach is not possible with NS7 (yes, is a different way than in NS 6.8).
I wish to have some time to test this with OpenLDAP.
If I understand well from @gabriele_bulfon in other topic when I put this question, they use WebTop as multidomain email server but in other configuration (not with NS).
Kind regards,
Gabriel
EDIT:
I found that topic!
and next …
