9. Sending Fax Using E-mail Clients

When sending an e-mail that should be converted to a fax, there are some points to keep in mind so that Faxserver properly processes the e-mail.

To header:
- must contain the subscriber’s number who is sending the fax, as the username part of the mail address
- must contain the specific domain starting with mail2fax.
Subject header: must contain the fax destination number
Body should consist of plain text data
Adding attachments is possible, but only plain text and PDF formats are supported

Secret Key

In order to use the "secret key" access control feature, it should be either put in the first row of the e-mail body followed by an empty line, or included as a plain text attachment. Once it has been validated, it will be removed from the email.

important
important	Either add the secret key to the body, or attach it. Never do both as only one will be recognized and removed, leaving the other one to be sent as part of the fax.

Mail Example

Provided there is a subscriber on sip:provider PRO platform with the 43130111 number, the destination fax is 43130222 and the secret key is "MySecretKey":

From: User Name <username@example.org>
To: 43130111@mail2fax.example.org
Subject: 43130222

MySecretKey

This is a test fax.
