Email to SMS: SMTP Interface Enhancement

We have enhanced the the ASPSMS SMTP Interface Email to SMS. When sending to [Recipient], the authentication is done through the senders e-mail address.

The new feature sends a plain text message to an SMS recipient. Usage:

From: [SMTP Originator Client]
To: [Recipient]
Subject: Originator=[Originator]
Body: [MessageText]

Subject: Originator=+41760000000
Body: Hello world!

The following applies:
The SMTP interface only processes ASCII Plain Text. Special characters must be encoded in ISO-8859-1 standard. HTML or other code are rejected. E-Mail and webmail clients that send HTML-encoded e-mails are unsuitable for testing (eg GMail etc.).

The subject is optional. If no originator is defined, the ASPSMS system sets the Originator 'SMS'.

Authentication is done by the sender's address (SMTP Originator)*. This e-mail address must be different from the address ASPSMS account e-mail. The address has to be enabled by the ASPSMS system beforehand.

Let us know which ASPSMS Account and which email address you want to use as your SMTP Originator. Once we have confirmed the activation, you can get started:

(* This implicit authentication by SMTP Originator means that the sender email address is the «secret» and not the usually used combination of Userkey and password. You therefore should choose an e-mail address which is different from the account e-mail address. It should not be self-explanatory and you have to keep this e-mail address secret, similar to your combination of Userkey and password.)
