petidomo/subscribe.c
Ralf S. Engelschall f9ec7fc9cb Sorry, I still inist that Petidomo visually resembles Majordomo as close
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.
