Bug#930059: kmail: Fails to connect to IMAP server using starttls: "plain login is disabled by the server"
Package: kmail
Version: 4:18.08.3-1
Severity: normal
After upgrading from stretch to buster, one IMAP resource stopped
working. Long story short, it turned out that it worked again when
switching from STARTTLS (port 143) to SSL/TLS (port 993). Unfortunately
STARTTLS (port 143) is selected after pressing the button "Auto Detect".
I confirmed the problem with a fresh user account. The full error
message when configuring with STARTTLS claims that the server refused
the supplied username and password, and says:
"login failed, plain login is disabled",
which is misleading, as it makes the user a) entering the username and
password again, thinking it may have been incorrectly entered and b)
trying other connection settings than "PLAIN" or "Cleartext".
The configuration with STARTTLS (port 143) has been working and still
works on stretch systems.
Thanks for maintaining kdepim packages!
