Scenario: I need to send out thosands of emails per day for forum thread subscriptions and about 100+ for new user registrations. I use Google Apps as my email provider.

Problem: Google Apps only allows about 500 emails to be sent per day, per account.

Attempted solution: create many email accounts and have a DTS job change the database holding the SMTP settings throughout the day. DTS runs fine and db is getting updated...

Problem with solution: DNN appears oblivious to the the changes most of the time. It seems to cache the SMTP login info. I understand why this is a good thing but it mucks me up.

Question: Is there some way I can schedule a process to make DNN reload the settings AFTER my DTS updates them?

Question: Is bouncing the the app pool the equivalent of an "Restart Application" in the host settings? If not, is there a programmatic way to accomplish this? Update the web config?

Question: Is there a cheap, reliable, secure SMTP service/server that you guys use for this sort of thing?
