I'm not usre what you mean by "clear out", but I'm guessing that you mean if
you can make multiple sends with the same attachement? How are you sending
the message, are you using the MailMessage class?
i was using the binaryreader.readbytes method on the
attachment.contentstream
then i later tried to save the stream and ended up with empty files because
i was supposed to reset the position to 0 after using readbytes
