When I tried to send mail from kmail using a DSL connection it failed with a 
message that authenication was required.  With the same SMTP settings, I 
tried again from mozilla, was asked for the mail account password, entered it 
and the message was successfully transmitted.

I double checked the kmail settings but found no way to enter the password.  
What is wrong?

My system is Debian Stable with a 2.24.28 kernel.  dpkg -p kmail reports 
Version: 4:2.2.2-14.6
