Kontact won't send email; Where's the og files?

Greetings

This difficulty really puzzles me. Kontact kan read email from the server just fine, but no matter what I do I can’t send anything. I’ve checked the relevant settings in [Tools] -> [Configure Kmail] -> [accounts] -> [sending] and they are identical to the ones I use with Pine. Pine have no trouble at all sending.

Anyone have any suggesions how to fix this?
For example pointers to log files or other relevant info?

Here’s my os and Kontact install
$ rpm -q --whatprovides $(which kontact) -i
