[Ultimate Branding] Network SMTP + optional SMTP per site

I'm happy to see that SMTP has found its way into the Ultimate Branding plugin. Yet a great improvement, from my perspective, would be to add an option to allow network sites to configure their own SMTP.

This could be useful for many situations, like:

– Sending a newsletter from a sub site.

– Sending order confirmations.

– For sub sites with members.

… To name a few.

Currently, as far as I'm aware, there is no SMTP plugin that allows to set a network default, which can be overwritten on a per site basis. I think it would be a welcome feature.

Thanks!
