To send faxes from your e-mail account, you will need to attach the document you wish to send in PDF format to a new e-mail, then send it to <fax number>@fax.neural.net.au
Steps to send a fax via e-mail:
1. Enter the fax number, including the area code with no spaces, dashes or brackets, followed by @fax.neural.net.au
2. Attach the document you wish to send (this must be in PDF format)
The subject line and e-mail body may be filled in, however they are not used and won't be sent as part of the fax -- only the PDF document will be sent.
