Hallo Zusammen,

seit einiger Zeit erhalte ich Emails von bestimmten Email-Absendern aus England mit bis zu 16 Stunden Verspätung. Dies betrifft sowohl meine Business-Email-Adresse sowie meine private Email-Adresse über T-online. Es betrifft nur Emails die über diese Art Header, wie den nachstehend anonymisierten Email-Header verfügen:

Woran liegt das? Meine Kollegen in England meinen, dass das Problem auf deutscher Seite liegt.

Vielen Dank für die Hilfe.
