Can't Send Mail

[Emily Dryden <dryden@verizon.net>]

I have a three computer home network connected through a router to a dsl 
modem.  Initial attempts to set up the email accounts with kde failed 
because konqueror could supply the user name for the smpt account but 
not the password.  Fortunately, mozilla could do both.  Now mozilla can 
no longer connect.  I suspect a security upgrade may have wiped out this 
feature.  Help!
