[Eisfair] fetchmail: - fingerprints do not match!

Hallo zusammen,

ich bekomme seit ein paar Tagen Fehler in fetchmail beim Abholen von Mails von Strato.
Vorgeschichte:
Am 18.03.21 gingen die Fingerprints nicht mehr. Kommt jedes Jahr vor also mit
fetchmail pop3.strato.de --ssl --verbose --username xxxxxx --protocol pop3
fetchmail pop3.strato.de --ssl --verbose --username xxxxxx --protocol imaop
die fingerprints ermittelt, eingetragen und neu gestartet. Alles wieder gut.
Am 19.03.21 waren dann wohl die Zertifikate abgelaufen also mehr Arbeit.
D.h. Zertifikate neu eingetragen gehasht usf.

Seitdem kommen nicht immer aber meistens diese beiden Mails im Eingang:

Mail-addon-certs certificate updater on 'mailserver'
Fetchmail event Report from Server 'mailserver'

Versenden geht einwandfrei. Ich bekomme auch die Mails, d.h. das ist nicht das Problem,
aber warum kommen meistens (aber nicht immer) die Fehlermeldungen.

Das Phänomen tritt bei 2 Mailservern seit 2 Tagen mit Verbindungen zu Strato auf.

Was kann das sein und weiss jemand Rat.
Dafür habe ich möglichst viele Informationen anschliessend zusammengefasst
(Domain und Passwörter geändert).

Viele Grüße
Harald Seitter
