Comment 5 for bug 1623381

Could you post the output of
$ ps aux | grep key

please? You can hide your user for privacy reasons if you want.

And could you check if the passwords you entered are stored in the keyring?

Easiest way to check is to install seahorse.

There should be a login keyring that has two keys:
org.pantheon.mail imap_username:<your e-mail>
org.pantheon.mail smtp_username:<your e-mail>
