PMDF System Manager's Guide

In order to support required IMAP4 features and desired POP3 features, the legacy mailbox IMAP and POP servers can create a special placeholder message as the first message in the mailbox. By default, the text of this placeholder message is:

This message contains information needed by the POP and IMAP servers to operate correctly. Please ignore this message.

If you want to customize the text of this placeholder message, you can create a file /pmdf/table/ignore-msg.txt containing your desired, site-customized text; the text of the file will be used in place of the default text.
