I have the same problem. On AIX 5.1... BTW you can use -DCOMPAT_43 when
compiling to get around the problems in unix_recv_fd as well... (Which
is what I did).

Did you get any further with this? I've got 5x mail gateways, all
supposedly identical, apart from IP addresses and only ONE of them
exhibits this fault using postfix-2.2-20040829-tls... I'm about to try
20041013 (Also with TLS, had to hand patch 4 rejects mostly in makefiles).
