I have set up an SMTP to SMS gateway for sending messages to a cellphone.
The problem is I need to set up multiple SMTP servers and be able to choose which one I use.
I can send SMS messages through the Gmail server allowing for both email and SMS alerts, but this isn't really a good idea as it allows anyone to send through my gateway.
If I can set up multiple SMTP servers in Mango, I can set up my gateway to only allow connections from the Mango sever.

Further to this it would be good if I could set up a different set of email templates for each SMTP server. Obviously a SMS alert has formatting limitations over email.

Cheers,
Matt.
