Bug#446346: exim4-config: incorrect condition in new configuration files causing bounced email

[Hamish Moffatt]

Package: exim4-config
Version: 4.68-1
Severity: grave
Justification: causes non-serious data loss

After upgrading exim4-config to 4.68-1 this morning I'm getting a lot of
messages bounced, with the following in the paniclog:

2007-10-12 20:59:41 1IgIEv-0005de-Ep failed to expand condition "${if ${match_ip{$sender_host_address}{:@[]}}{1}{0}}" for real_local router: condition name expected, but found "${match_ip{$send"

This comes from the new conf.d/router/300_exim4-config_real_local:

COND_LOCAL_SUBMITTER = "\
               ${if {match_ip{$sender_host_address}{:@[]}}\
                    {1}{0}\
		}"

I don't know in what way this is wrong but I've disabled the condition
for now. 

I have "deliver real-hamish" at the end of my .forward which is
triggering this. I guess nobody else does this as nobody has reported it
until now.

Thanks
Hamish
