AFAIK the auto-reply (e.g. out-of-office notification) functionality of Mercury could only be controlled by Pegasus which is adapting and changing the file extension of the "areply" file.
In the meantime more and more colleagues retire Pmail and replace it by Thunderbird which is collaborating great with Mercury.
But a simple adjustment of Mercury's auto-reply function by another Mail client is missing.
Either we have to keep installed another Pmail installation, only started for switching the areply function, or we have to edit the areply file manually. But we don't want to grant every user full write access to its mailbox directory.
Are there any other solution in place?
