KMail currently doesn't handle different authentication methods for=20
different encryption methods correctly.

At least here KMail prints the answer that it receives from the server=20
during the "Check what the server supports" run to stdout. So if you=20
run KMail (compiled with debug information) from Konsole then you=20
should get something like the following:
kmail: IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS CHILDREN=20
LANGUAGE STARTTLS XSENDER X-NETSCAPE XSERVERINFO AUTH=3DPLAIN

kmail: IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS CHILDREN=20
LANGUAGE XSENDER X-NETSCAPE XSERVERINFO AUTH=3DPLAIN

The first line is for port 143 and the second one for port 993. KMail=20
will only use the first line. This should explain the behavior that=20
you've noticed.
