Some message are shown in IMAP client but NOT in WebMail overview: Hide reason?


  • I have an email account at and I am accessing it in two ways:

    Through browser with webmail frontend and secondly through local email-client (Thunderbird) through IMAP.

    Much to my surprise there are lots of messages appearing in the email client which do NOT appear in the messages list in browser webmail.


    Both email lists are sorted by date (newest topmost). 

    A corresponding auto-move messages with sender A to customized folder B is NOT set up.

    What else can be the reason?
