    As of last Friday, Postie access through IMAP stopped working. I turned on full debugging and the last status message is:

    Unable to connect. The server said: IMAP – Could not connect to IMAP server imap.ionos.com on port 143. Array
    (
    [0] => * BYE out-of-sync data before server greeting
    )

    I have used telnet to access the email account using imap and it works fine. Here is the telnet output (with the account name and password obscured):

    [~] telnet imap.ionos.com 143
    Trying 74.208.5.6…

    Are you using cUrl or Sockets? If you’re using cUrl please try sockets, it is more reliable.

    When you tested via telnet was it from your local computer or the server hosting your WordPress instance. If local please try again from the web server.

    I used sockets. I used my local computer for the telnet test, but I can’t use the web server, since it is a shared host (Ionos) and I don’t have access to a command line.

    I suspect you’ll need to contact your hosting company. There haven’t been any changes to the IMAP portion of Postie for years, so something on the server must have changed.

    I will contact the service provider, but past history suggests the support given is by those who read from scripts, rather than possess any understanding about the underlying technology.

    One thing I noticed. The problem began shortly after the hosting provider auto-updated to WordPress 5.8.3. Has the plugin been tested against this version of WordPress?

    Yes. Postie is compatible up to the current 5.9 version.

    For the record, it seems it was a particular email message that was causing the problem (an update message from Envato Market announcing a new version of the Enfold Theme). Once I deleted that message and tested with a new message, it all worked fine.
