Hi, I've found workaround for bug with SMTP error. Jolla-email app tries to send messages with sender email address equal name that is defined in account configuration as a "POP/IMAP user name". I have no idea why someone implement this in such way, but accidentally it works correctly in case Gmail - Gmail's "POP/IMAP user name" is the same as email address. Unfortunately I am not a Gmail customer and in my case it doesn't work at all. I am unable to send emails form Jolla native app. Solution: Email account configuration is stored in "/home/nemo/.config/libaccounts-glib/accounts.db". This is sqlite db and can be edited with standard tools like sqlitebrowser. Email address is defined in "Settings" table and key = "emailaddress". I've changed it to my correct email address and it fixes the problem with SMTP.
