Deutsche Post har ikke kun haft en dominerende stilling i forbindelse med de tjenester, der var omfattet af eneretten (i henhold til § 51 i PostG 1997), men også i forbindelse med næsten alle andre brevposttjenester, der allerede var blevet åbnet for konkurrence.
Deutsche Post has had a dominant position not only with the reserved services — pursuant to Article 51 PostG 1997 — but also with almost all other letter services which have had been opened up to competition.
