There is no such thing as "seen" status in POP3.
POP3 determines what is a new message or not via unique identifiers (UID) assigned to each message. A message with a UID not previously seen by the POP3 client is considered to be "new" and is downloaded.
Some very old POP3 clients (e.g., ancient versions of Eudora) look for a Status: header line. ipop3d will write a Status: header in the message with the IMAP "seen" status as "R", and the oppose of IMAP "recent" status as "O". But nothing modern does this.
If you are still using the traditional UNIX mailbox format, it is possible for flags changes to be lost if your webmail client disconnects the connection without issuing a proper LOGOUT command first. Check your mail logs to see how the webmail sessions are terminating. Also note that if a session opens a mailbox while the mailbox is already open in another session, the new session will kill the old session. Both of these problems are avoided if you upgrade to a better mailbox format such as mix or mbx.
If, on the other hand, ALL messages (including messages previously downloaded with POP3) are marked as "new", this may indicate some problem that is causing a rewrite of the UID. However, I will need more information about your environment in order to proceed further with a diagnosis. For example, what mailbox format are you using?

Hello, We noticed some strang behaviour when using imap 2007. When we used imap 2004 a client could read his e-mail externally with a webmail application (it's using an imap connection), when he came to his desk to download his e-mail with pop3, the e-mails that he already had seen in the webmail application were still marked as 'seen'. Now with imap 2007 the e-mails are always marked as New in his inbox after downloading with pop3. I tested with outlook and eudora, the results are the same, also test the latest development release. Is this behaviour ment to be permanent or can it be fixed ? best regards, Andres Henckens _______________________________________________ Imap-uw mailing list [email protected] https://mailman1.u.washington.edu/mailman/listinfo/imap-uw
