fetchmail (6.4.23-1) unstable; urgency=medium

    For common ssh-based IMAP PREAUTH setups (i. e. those that use a plugin
    - no matter its contents - and that set auth ssh), change the STARTTLS
    error message to suggest sslproto '' instead.
    This is a commonly reported issue after the CVE-2021-39272 fix in
    6.4.22.
