There are some known issues, but they are not bugs:
1. Mails in sent folder disappeared after sending a mail. It is not a bug, please read the NOTE above, perhaps you should modify your filter defines.
2. It autorun on all accounts after sending a mail. It is the correct action, now this addon has only a global setting for enable or disable, can not be set to a special account.
3. Filters are repeatedly executed on same message. It is not a bug, this add-on execute the filters on the folder but not on the certain message. There are simply ways to avoid repeated filtering.For example, add a "tagging" action to your filter definition, then add a "not containing tag" to your filter's condition definition. Another way is similar with adding tag, moving all outgoing messages to other folder by a filter and then ensure that there are only new messages in your sent folder.
4. Someone reported that it can not work well, so please mail to me and Ｉ will try to find out reason.
Please mail to me but not comment here if you have any problem!!!
