no the failure mail will put the reason.
A lot of words there but U just have to read it once to know where
the reason is located.
means that ur email send out mail but kenna bouce back for whatever
reasons...maybe the other party's server busy....mailbox
full....etc...
to find out how to stop that....find out the reason first from the
failure mail.
if U totally dun want to receive failure mails....then U have to
set ur filter to get rid of them....takes a little tweaking
though...
