I have problems sending mail from a ruby production app on heroku by a gmail smtp account.
When i apply the solution all works wel, but after a while the problems comes back.
Do i have to set something in my google account to make it permanent ?
I think it has to do with the fact that i am using a free heroku account. The servers stops after a while an perhaps has to login in gmail when it starts up again.

There's no way to make it permanent because Gmail doesn't want its service to be used to send out automated e-mails(*).
There are some providers that will make it much easier for you:
- https://sendgrid.com/pricing/ has a free plan (up to 100 emails/day)
- https://postmarkapp.com/pricing gives you 10k emails for 10$)
or take your pick, because the market seem to be pretty saturated: https://duckduckgo.com/?q=e-mail delivery service&ia=web
(*) What I suspect they do (though I could not find info about it) is that they can see if "same e-mails" are sent within short intervals.
You might try your luck (if it makes sens, when for example it's a toy project) to alter each e-mail contents to make it seem like different e-mail each time. But it will be just easier to go with free option in any other providers that actually want you to use it in your app.
