Things to try:
- disable chroot for THAT smtpd on port 10030
- check that you have enough instances of that particular smtpd (otherwise mailman must wait until one is available)
- check the restrictions for that particular smtpd
- try connecting manually!
No, chroot, default number of processes (= 100, far away from that), no restrictions...

But... damned - I got it:
root@mail01.foodmz.local:/var/log/mailman# telnet localhost 10030 Trying ::1... Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mail01.foodmz.local ESMTP Foo ready
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!!!!
