I recently upgraded my exim server, and now I can’t send mail through k-9. It works fine through thunderbird, so I expect k-9 just has a more limited way way of authenticating.
The server is set up to connect to port 587, encrypt via STARTTLS, and then do a plaintext login.
The error I’m getting from k-9 is “Authentication methods SASL PLAIN and LOGIN are unavailable.” Which is odd, because I’m pretty sure everything’s set up to work with plain text logins using STARTTLS. Again, it works just fine that way in Thunderbird.
Has anyone else seen something similar? I imagine there’s some exim config that I can change to fix it?
