Enabling encryption for fax confirmations sent by InterFAX

This feature will add another layer of security to your communications with InterFAX. When you send faxes through the InterFAX email-to-fax service, you may choose to receive confirmations upon success of a transaction, on failure, always, or never.

These confirmations are standard email messages which are returned to the original sender address of the email-to-fax. Under normal circumstances these messages are sent in an unencrypted format; however, it is possible encrypt these messages. To encrypt the feedback messages being sent to you, we need to have your digital signature.

Send InterFAX your public key signature

This step only needs to be done once.

Send a signed (not encrypted) email message to digitalid@interfax.net from the email address from which you intend to send your faxes, and InterFAX will automatically associate the sender address with this digital signature. Any feedback returned to this address will from then on will be encrypted.

Note: This will also encrypt inbound fax messages if there is an inbound service active, see below for more information;

To cancel encryption, simply send a second unsigned email message to digitalid@interfax.net.

  1. Complete the instructions above then login to your account.
  2. Navigate to My Settings / Incoming Options / Notifications.
  3. Use the More options link next to the appropriate email address and click on Edit.
