Maybe im just out of it, but I did not receive an attachment with this mail,
nor do I see any code within the mail body. Some of your complications sound
too weird to explain in a general sense for what could be causing the
problem, so we would need to see the source to look for major screw ups...
Dont worry about posting your code here, because its not like anyone would
want it anyways, with such problems in it at this time... :>
