Email to SMS - Customized solution

There are so many email to SMS server companies around, however what I need is a bit customized. These companies require that the email should be sent to <number>@domain.com. However, I have a software which has limitations, it can only send to one email address defined <fixednumber>@domain.com. I would like an Email to SMS server, which will take my email like below example (## is used as indicator character): To: <fixednumber>@[login to view URL] Body: xxxkkkkkkkssssskkkk trash text ## +19723000000 ## Thank you for your stay, this is the text to be sent to recipent ## ssssddddddddd trash text I used # as indicator, however other formats can be used to find the number and text in the email. The solution should extract those from a plain text or HTML email. And if recipents answers, the answer should be emailed back to the sender of email (me).
