as possible: now Petidomo no longer just sends a carbon-copy of the final "successful" mail after subscribe/unsubscribe operations to the list owner. Instead the list owner gets an own dedicated mail. The most important thing is that those mails have "SUBSCRIBE" and "UNSUBSCRIBE" tags in their Subject so one can easily monitor those operations as the list owner.
