Regular Message Deletion From Users' Mail Files

Mail servers are usually short of disk space due to constantly received and
sent messages.
To overcome this notify your users about a message deletion strategy and
implemented that within a Lotus script in each mail file.
The following code is written based on a strategy of deleting messages which
are older than three months from both the Inbox folder and the Sent view. The
script sends an email message (eventhough it appears to be sent from the users
themselves) saying that messages older than three months will be deleted after
the users' 10th login to their Inbox, to give them time to archive important
messages. You can customize the code as to your strategy.

You can put this code in the mail file template of your system, mail46.ntf or
mailc46.ntf. I put it in the Folder design, ($Inbox) view, Postopen event for
the Inbox Folder. Once you do this you can replace the design of users' mail
file using the following command from the server console:
Load Convert -s mail\*.nsf StdR4Mail mail46.ntf(the -s parameter will preserver
any customizations made to mail file designs by users)
or if the Design task runs according to a schedule it will refresh the design
of the mail files the next time the task runs
