There is a smell of IPv6 here.
What is a DNS lookup of localhost giving you, or whats in your 
/etc/hosts file or however you get your name lookups?  I assume you are 
getting both a IPv6 loopback and a IPv4 loopback address, in which case 
there are 2 solutions:-

  1. Get postfix to support IPv6 and specifically listen on the IPv6 
loopback

  2. Rehash your name lookups so that a localhost lookup only returns
     127.0.0.1

  3. [my counting is dodgy]  Change the host that Mailman connects to 
via SMTP
     to an explicit IP by adding
	SMTPHOST=127.0.0.1
     to mm_cfg.py

	Nigel.
