No, chroot, default number of processes (= 100, far away from that), no
restrictions...

But... damned - I got it:

The machine is IPv6 capable, but Postfix is listening to IPv4. As
Mailman is configured in mm_cfg.py to use "localhost" for injecting
back, it gets back "::1" first, tries to connect for 20s, and then falls
back to IPv4, which then succeeds.

So I simply added in my /etc/hosts an entry called localhost-ipv4 for
127.0.0.1 and took that for SMTPHOST in mm_cfg.py.

And, what should I say... like a rocket!

Thanks a lot to all of you for assisting me!!!!
