Email to SMS
Email to SMS service enables you to use your current email programme (MS Outlook, Gmail, etc) to send and receive SMS messages. It is a powerful tool for office communication.
Emails sent to, for example, 447797803200@bulksms.net are forwarded via the BulkSMS system as an SMS text message to the mobile number 447797803200.
AQL is a typical EMAIL-to-SMS provider which you can use it in DualShield.
If you check its configuration file aql.xml,
<smtp> <email>${to}@text.aql.com</email> <format>text</format> <from>${from}</from> <subject>${subject}</subject> <body><![CDATA[${body}]]></body> </smtp>
It only has the recipient setting ${to}@text.aql.com .
Do you ever wonder which smtp server Dualshield uses to send the OTP(or other information) out to ? or by magic?
In this case, you have to configure a SMTP gateway before setting up AQL-like SMS gateway. At least it is correct by the time this article is published (25/04/2013).
In addition, one of our customers reported a problem "Message gateway is not available, please try again later" when using such a gateway. We checked the log, and found another message "501 5.1.7 Invalid address". it turned out their SMTP server refused to send out a message which has a non-legitimate sender address.
