I have problems sending mail with one of my clients (a Nokia 9210
communictor). I am quite sure that this was working before I upgraded
to exim 4.60. The main problem is that I do not really know how to
interpret the error message. Here is exims log information:

I understand that exim gets the command "AUTH LOGIN" and then sends
the prompt "Username:" ("VXNlcm5hbWU6" base64 encoded); this is fine
and exactly what exim should do. The next thing exim does is send the
message "501 Invalid base64 data". In between those two last
statements in the log there should be the username sent from the
client; is it possible to enable some debugging option that will show
the username and password sent by the client? And: What is the message
"501 Invalid base64 data" related to? To the username exim received
from the client or to something else?
