Current:
-* Implement encoded-character extension
+* Implement variables extension.
Next (in order of descending priority/precedence):
-* Implement variables extension.
* Finish implementing all extensions supported by cmusieve, except notify.
* Limit the maximum number of errors.
* Verify outgoing mail addresses
