@brylie These is resovled issue. But I have the next information in meteor console:

====== BEGIN MAIL #0 ======

(Mail not sent; to enable sending, set the MAIL_URL environment variable.)

[brylie]

Right, the mail settings have to be configured in order for the MAIL_URL environmental variable to be set.

[brylie]

We have enabled verification emails at all times, which means that Meteor will sometimes try to send emails when the MAIL_URL environmental variable is not set. This is intentional, for now. We have a follow up task #1843

[marla-singer]

This is intentional, for now.

So, should I merge it? When MAIL_ENV is not set, email doesn't send to user.

[brylie]

Jep. That is expected. We have to figure out how to dynamically enable the email related features, but in the meantime opted to enable them by default.

@brylie I'm goint to merge it with a view to MAIL_ENV will be set and will work correct in the PR for 1843 issue
