How can I configure the smtp port used by Accounts.ui in Meteor

Question

I am unable to send email in development because cloud9 blocks normal smtp ports. Can I configure Accounts.ui in Meteor to use mailgun's special smtp port?

Answer 1

It's done with an environment variable like this

MAIL_URL = "smtp://user%40gmail.com:[email protected]:465"

The first @ has to be written as %40 - to do with the way the url is parsed
