We own the servers and use CT (LXC).
The IBM move is clear, but going to C7 today seems to me not a good 
choice. 
It is in its descending stage and in a couple of years packages are going 
to became very outdated.
If RH8 remain "open source" I suppose the community or some interested 
medium level company that use CentOS for their business can became a new 
CentOS and switch to a different named distro is supposed to be only a 
question of replace repositories.
That seems to me a smoother path (IMHO).
Debian 10 is EOL on 2022
Ubuntu LTS seems a solution, but I hadn't ever used it (I may be wrong, 
but in the past Canonical don't inspire me to much trust).

Other options (not too "exotic")?

I am studying the situation, but there are many variables and the old age 
of the source server probably meke it more complex.
And I am not a dovecot expert ...

Thanks, B.
