[Dovecot] inetd & corrupt environment

[Gelu G. Lupas]

Hello. I'm having the following problem with dovecot 1.0.12 and above, 
on a FreeBSD 7.0 system - I'm trying to run pop3-login from inetd and I 
keep getting this error after authentication:

May 25 09:46:19 charlie dovecot: POP3(gelu): /libexec/ld-elf.so.1: 
environment corrupt; missing value for no-nuls oe-ns-eoh

The problem persists if I uncomment the lines with no-nuls oe-ns-eoh in 
dovecot.conf. I've also tried running pop3-login from 
tcpserver/ucspi-tcp and I still get the same error.  Version 1.0.1 works 
fine on a similar setup. Please reply if you have any idea regarding a 
fix for this error. I need to run dovecot under a tcp wrapper of some 
kind (preferably inetd) as the standalone daemon doesn't allow any 
method to restrict access by IP. The allow_nets extra field doesn't help 
much as I'm using PAM and do not want to maintain yet another passdb. 
Restricting access via firewall rules is not an option. Until I find a 
way to restrict access by IP address, dovecot will only listen on the 
private IP address (192.168.100.1).

My dovecot configuration follows:
