Hello,
I have installed hmailserver v5.3.2 + roundcube v0.3.1 and roundcube v0.4b.
My problem is same in both 2 roundcube's versions.
The function 'Sender notifications' doesn't work.
The interface doesn't ask me to send. (option selected: ask the user)
however in the source of the mail 'Disposition-Notification-To' is indicated.
Anybody can help me or guide me where to search ?
thank
hMailserver does not support $MDN flags yet. So Roundcube is not able to handle MDN requests. Raise a feature request on hmailserver forum.
