I am AMAZED at what people come up with. I would NEVER have thought

BUG! Fixed in next release. Here is a patch:
*** common/linelist.c 2002/02/28 18:12:09 1.13
--- common/linelist.c 2002/03/02 18:25:12
***************
*** 2611,2616 ****
--- 2611,2622 ----
char *s;
DEBUG1("Make_passthrough: cmd '%s', flags '%s'", line, flags );
+ if( job ){
+ s = Find_str_value( &job->info,QUEUENAME, Value_sep );
+ if( !ISNULL(s) ){
+ Set_DYN(&Queue_name_DYN,s );
+ }
+ }
Init_line_list(&env);
if( env_init ){
Merge_line_list(&env,env_init,Value_sep,1,1);

You have ^M at the ends of lines, perhaps?
Bad file? Gremlins? Leprecauns on a drunk?
When this happens, COPY the /etc/ifhp.conf file to a new location.
cp /etc/ifhp.conf /etc/ifhp.conf.evilfile
Now edit/change it as above. See if this works. If it does, do:
cmp /etc/ifhp.conf /etc/ifhp.conf.evilfile
If they are identical, buy a bottle of Tullamore Dew and execute
the following Dew loop:
while( concious ){
pour glass of Dew;
drink Dew;
}
