Stripping text before a dash in the subject line as done by postie for setting a category confuses some users. Therefore I would appreciate either
Make it configurable (wether text in dashes is taken for a category)
Leave the subject line “as is” in any case
Leave the subject line “as is” if no matching category is found
Maybe the same is reasonable for text left to a colon – we just didn’t have troubles with that yet. We would however like to keep the "category left to a colon" feature while disablling the "category between dashes" syntax.
