My guess is that your message-id like this: Message-ID: <8b21e2aa979f8c1944fc0b5ca4be1e5c@posteo.net> is generated by your sendmail program. I use msmtp which has an option: =E2=80=98set_msgid_header [(auto|off)]=E2=80=99 When to set a Message-ID header: =E2=80=98auto=E2=80=99 adds a Message-ID= header if the mail does not have one (this is the default), and =E2=80=98off=E2=80= =99 never sets a Message-ID header. Message-IDs have the form =E2=80=98hash@domain=E2= =80=99, where =E2=80=98hash=E2=80=99 is a hash over some values that uniquely identify = the mail, and =E2=80=98domain=E2=80=99 is either the value of the domain command (unles= s that is the default value =E2=80=98localhost=E2=80=99), or the domain part of the env= elope-from address (if available), or the host name of the SMTP server. Maybe you want to check your sendmail program. Best, Arash
