</span>Hmm, interesting. I think there are three times otrl_message_sending<br>
would output the default query message:<br>
<br>
- If you pass the string "?OTR?" or similar *into* otrl_message_sending.<br>
<br>
- If your policy has OTRL_POLICY_REQUIRE_ENCRYPTION set, but the context<br>
msgstate is still at OTRL_MESSAGE_PLAINTEXT.<br>
<br>
- If you receive an OTR Error messaage, and your policy has<br>
OTRL_POLICY_ERROR_START_AKE set.<br>
<br>
Could you possibly step through otrl_message_sending and see which it<br>
thinks is happening?<br>
<br>
Thanks,<br>
<br>
- Ian<br>
