I've managed to fix my problem of only being able to send 8mb attachments, i've changed my php.ini file to allow "post_max_size = 128M", but i've tested it with a 20MB attachment, the email was sent but i received this error instead of the $GoToPage:
It doesn't add up, the memory limit is 128MB, and it's exhausted the limit at 28MB??
What have i done wrong now??
btw. still no luck with the progress bar.. :( any ideas?
