New version 0.3
I added a second subject configuration line.
Now you can set different subjects for incoming
and outgoing messages.
And another variable $(RECEIVER)
When forwarding incoming messages
$(SENDER) is replaced with the senders id and
$(RECEIVER) is replaced with your id and
when forwarding an outgoing messages
$(SENDER) is replaced with your id and
$(RECEIVER) is replaced with the receivers id.

For example, you can make this subject lines:
outgoing : $(SENDER) -> $(RECEIVER)
incoming : $(RECEIVER) <- $(SENDER)
