I have a laptop running KMail 5.7.3 on Bionic Beaver. I just got a new computer with Eoan Ermine and am trying to set up Kmail 5.11.3 to use the same IMAP server. I set up the IMAP account, tried to view my email, and got this error:
The server for account "IMAP Account 1" refused the supplied username and password. Do you want to go to the settings, have another attempt at logging in, or do nothing? SASL(-4): no mechanism available: No worthy mechs found
I set it to plain text (which is safe since the server and both clients are in the same house) and ran Wireshark and captured this:
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready. A000001 LOGOUT * BYE Logging out A000001 OK Logout completed.
It didn't even try to log in! How do I make it work?
