spurious but frequent failures with smtp.openmailbox.org
after configuring smtp.openmailbox.org (which has some hurdles - like login name must be [email protected] and sender name must match it exactly, no shortcuts, aliases etc) it mostly works.
However - in 1 of perhaps 5 cases I get this error:
"Authentification failed. Please check your username and password!"
"try again" usually works.
The errors are just too frequent to think it is a random failure, already had over 20 in 3 days. Never had this type of failure while using google smtp when used in similar conditions.
The network connection is sometimes extremely slow - but that should not cause above error message?
Tested on a Moto G with freshly updated system.
Sorry, I don't have a openmailbox.org account to test with. You could check your logcat output for more information and if there's nothing ask their support to tell you what they see from their side for the time you try to connect.
Found only this, a few seconds tried again and it worked.

it works - but out of 10 times 2-3 times it fails with "Authentification failed" which is the mysterious part. After retrying it usually works again, sometimes I have to retry several times.
It is really mysterious. I can only suggest to get in touch with your provider to get to the bottom of this.
