email send authentication failed

For some reason all of a sudden Indigo is no longer able to send me a power failure email. The only thing that has changed is I upgraded my controller to a 2413U. I've been using my iCloud account for this for a long time. SMTP server is correct as is address and password. I re-entered all the info, quit/restarted Indido, shutdown/restarted computer, still no go. Any thoughts? Is it anything to do with authentication on Apple's side? Again, this was working up until I swapped out the controller this week.

iCloud now, for a couple of months at least, requires app specific passwords. I had to generate one for Indigo to continue receiving emails. Have you looked into that?

I'm pretty sure that's what the problem is, I thought it was probably due to the new two-factor verification but couldn't remember the details. Thanks!

Re: email send authentication failed

Thank you for this information. I recently had to change my AppleID passwords... something I'd been meaning to do anyway. When I did I discovered that Indigo quit sending emails.

Going to AppleID at http://support.apple.com/en-us/HT6186 solved the problem, creating a new app-specific-ID.

This is something that you don't do every day... maybe once every year or two if that. Specifically, what fixed my problem was to go to the link, click on "App-specific passwords" link, generate a link which I named "Indigo Email"... and Apple gave me an App-specific password that I was able to paste into the "SMTP password:" of Indigo's Email Preferences. This was actually a little counter-intuitive to me... app-specific password does not really say "EMAIL SPECIFIC PASSWORD" to me.... but that's where you paste it.
