Access was granted under the following conditions:
Opening access for electronic communication via De-Mail
The De-Mail address poststelle [at] polizei-duesseldorf-nrw.de-mail.de (poststelle[at]polizei-duesseldorf-nrw[dot]de-mail[dot]de )has been set up for electronic communication with Düsseldorf Police Headquarters via De-Mail. The transmission of De-Mails is possible for both informal and formal correspondence.
If the written form is required by law for certain letters, a handwritten signature would generally be necessary on your part. We have opened access for e-mails that require the written form. This replaces your handwritten signature. For the legally binding electronic sending of documents requiring written form, please use the De-Mail sending option in accordance with Section 5 (5) of the De-Mail Act. The legal requirement is fulfilled if the "sender confirmed" sending option was selected when sending the De-Mail.
If you send us a De-Mail, we assume that you also wish to receive a reply to this matter by De-Mail. If you close your De-Mail inbox again, please let us know so that we can stop communicating with you by De-Mail.
Further information on De-Mail can be found on the BSI website.
Opening access for encrypted electronic communication
The Düsseldorf Police Headquarters offers an encryption procedure for electronic communication with the email address poststelle.duesseldorf [at] polizei.nrw.de (poststelle[dot]duesseldorf[at]polizei[dot]nrw[dot]de). The public key (certificate) is provided here.
Encrypted communication with an organizational unit of the Düsseldorf Police Headquarters or directly with individual persons within the authority is not permitted. If Düsseldorf Police Headquarters replies to an encrypted email, this will also be done electronically, provided Düsseldorf Police Headquarters is technically and organizationally capable of doing so. Otherwise, the reply will be sent by another suitable means.
