With everything configured at IPBrick, we can send a SMS(s) using a mail client or webmail using the syntax:
<prefix + number>@<mail2sms domain>
E.g.: We are using the domain sms.domain.com and a VipVoz account activated with prefix 00. To send a SMS to the Portuguese mobile number 946666666 saying 'Hello, party at 23:00 - Bar XYZ'.
To: 00351946666666@sms.domain.com Subject: Party Body: Hello, party at 23:00 - Bar XYZ
Note that you can create a mailing list at IPBrick and insert all the mobile numbers you want. E.g.: Create a mailing list named smscostumers@domain.com and insert at External users list some costumers mobile numbers:
00351222222222@sms.domain.com
00351213333333@sms.domain.com
00224545345345@sms.domain.com
...
So at the client side you just need to send a email to smscostumers@domain.com, with the text you want.
