David, are there any circumstances when MD will not write out a HEADERS
file? I've got mail passing through the system that my code in
filter_begin doesn't seem to see.
...
if ( open(HEADER, "<HEADERS") )
{
while(<HEADER>)
{
next unless /^(To|From|Cc):/;
if ( /mx\.sonic\.net/i )
{
md_syslog('err',"found hostname in header:: $_");
}
}
close(HEADER);
}
else
{
mdsyslog('err',"couldn't open HEADERS for hostname information :: $!\n");
}
...
I don't see how this code could fail - and yet it is. Is it possible that
I'm encountering a char set issue -- most of the '[EMAIL PROTECTED] spam' I see
is coming in from .tw in a multi-byte charset.
