Yes, in the OP. In case you missed it:

 "Why Debian does't have a switchable MTA mechanism
  to allow install multiple MTAs at the same time?

 "Fedora, Centos etc. allow users to install
  multiple MTAs at the same time.
  There's a "alternatives --config mta" command
  to allow to choose between alternative MTA."

I think Andrei answered it in the third post of the thread:

 "Installing and removing/purging packages has traditionally been very
  easy in Debian, such a mechanism would have limited benefits for
  significant added complexity."

I have no experience of Fedora installations myself.

Then, as frequently happens, the thread expanded into such options as
distributing different tasks, that one MTA normally does, amongst
several different MTAs. Even more complexity. No thanks. Configuring
just one is enough for me.

Cheers,
David.
