SMTP Errors in Local Dev

[artasparks]

I'm getting errors related to SMPT mailing in local dev. This happens any time I try to do a login/ registration.

@brilee -- does this happen for you too? Do we need to change the value of the following?

MAIL_SERVER=smtp_server.usgo.org

Full error example:

The SMTP stuff has to be connected to a working account. The app sends an email to confirm that you've registered - that's probably the part that was throwing an error for you during registration. I should have made the placeholder email address more clear; in production that env value is set to Amazon SES, and locally I test using a throwaway gmail account.

I don't know enough about how email works to say if there's a sensible default localhost-ish configuration that would work out of th ebox.

From Amazon SES account.
Sending Quota: send 50000 emails per 24 hour period
Max Send Rate: 14 emails/second

I think we can get away with using that for dev testing until everything is fine. If need be we can up that limit.
