You can send a fax from your mobile device by logging in to the email account that you use with Fax Thru Email on your mobile device. The "From" email address in your mobile mail must be the same as the email address in your Fax Thru Email account.
The "From" email address must match the "Account Email Address." Fax Thru Email checks that these two addresses match when validating the outgoing fax. If you enabled the Remote Faxing Password feature, the system checks to ensure the password in the subject line of the email message is accurate and valid.
