It seems there is a relatively major issue with email going on. There's a number of threads.
- I've been using the same mailgun setup for like 2 years, have never had this happen
- I don't think I changed my setup at all (same 1.4 meteor version, same email package)
- a fresh server will send an email, but then all other emails will not send
- no error is thrown in a try/catch block
- mailgun shows the same behavior
- mailchimp shows the same behavior
- mailchimp logs do not show an email in the logs, so it seems that my meteor server is never sending it out
