Right now, you can specify 1 SMTP server on the company level and 1 SMTP server on the user level. A user can be assigned to send emails though either, but not both.

I propose adding the ability to specify multiple SMTP servers on the company level.

Then, the ability should be added when creating EVENTS to allow the selection of one of the multiple SMTP servers if an email event is being created.

You should also be able to choose while SMTP server Mass Email would use, while still maintaining the override on the user level.

This would allow different events and processes to use different SMTP servers.

Customer facing emails could be sent through one service and internal only emails could be sent through another.
