Yesterday I was thinking about the process of copying mailbox data from an old Pegasus Mail installation to a new one. When I have done it in the past, I have copied the .PND files (POP3 and SMTP host configuration files) to the new installation without a thought to including the POP3 associated .PM3 file (the file that keeps a record of retrieved messages). In theory, without the .PM3 file the first POP3 retrieval by the new installation should have brought down all messages on the server. I don't recall that ever happening though. Only the messages received since the last POP by the old installation were retrieved. Can any explain this and how the .PM3 file fits into the process?
