Fax SMTP – Basic Usage
This section explains the basic usage of our fax SMTP gateway for automatic faxing.
The minimal requirement for initiating a fax is sending an email with the following parameters. The resulting fax will be a plain-text document whose content is the email body.
This address is used for authentication. Therefore, it must be an “allowed sender” address in an InterFAX account.This address will also be used as your fax identifier (CSID), i.e. this is what the recipient will see on the LCD screen of his fax machine.
PHP Developers note: When sending an email to fax from PHP it is not enough to set the “From:” address in PHP’s

|Body||String||This is the body of the fax. Text may be any length. Format may be plain text or HTML – if both are present, HTML will be faxed.|
