courier-imap-4.3.0 breaks connecting/logging in for some users

[Stefan Bethke]

Hi there,

just a quick observation since I don't have time to fully debug this  
tonight:

On 6-stable from mid-October 4.2.1
<ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6.3-release/mail/courier-imap-4.2.1,1.tbz 
 >

works fine, but the most recent port
# $FreeBSD: ports/mail/courier-imap/Makefile,v 1.122 2007/12/12  
15:51:28 oliver Exp $

breaks connecting/login for some users with some clients, at least.

No errors are logged (or I can't find them but I was looking at  
*.debug) for the clients that don't work. Clients (squirrelmail, Apple  
Mail, Thunderbird, fetchmail) appear to report a dropped connection  
and/or wrong user/pass.

Anybody else seeing this? How can I convince couriertcpd/imaplogin/ 
couriertls/imapd to produce *any* log output for those connection  
attempts? Googling around I only found suggestions to start strace/ 
ptrace'ing processes, and I find that a rather annoying method to find  
the root cause.


Thanks,
Stefan
