Qmail & Qmail-LDAP future

Dear colleagues of QMAIL and QMAIL-LDAP

I have a very stable Qmail-LDAP solution for more than 10 years.
I have HW balancer with Qmail-cluster (N nodes)
The fact is that I think that this project is discontinued and it seems a pity.
Qmail is the best MTA there is but his design, in my opinion, is pretty bad. This was compensated with LDAP, which provides us with all user management in a flexible and powerful DB.

The problem is that if there is not a Qmail-LDAP continuity project and updated patches, I do not see any future. 
I am worried that in the future some kind of vulnerability will appear and that there is no solution.
For example, I don´t have any solution for submission implementation, DKIM, etc. to be integrated with Qmail-LDAP

I thinking to change to Qmail –> Netqmail –> https://notes.sagredo.eu/en/qmail-notes-185/patching-qmail-82.html and I would not like it because for example I would have to use vpopmail again (Software discontinued too since 2011)

What’s your opinion?
