Legal notice
Translation. This is a courtesy translation of the German Impressum. In case of doubt the German version prevails, because it is the one that discharges the statutory duty.
Legal framework. This site is operated from Germany. German law therefore applies to the mandatory information given here, and every reference to legislation on this page is to German provisions. For visitors from other countries this means: these details are not a formality but the legally required provider identification — it says who is responsible for this site and how that person can be reached.

No telephone number is given. Under the case law of the Court of Justice of the European Union, a further route alongside the email address suffices provided it enables rapid and direct communication; the contact form fills that role. Enquiries made through it are answered just as emails are.

Nature of this site
mailv1.com is a private, non-commercial information site. No service is offered, no goods are sold, no advertising is displayed and there is no payment from third parties. There is no company behind the site; the natural person named above is responsible.
There is no VAT identification number under § 27a of the German VAT Act.
How the content is produced
The texts and illustrations on this site are produced by an AI system (Claude, Anthropic) and reviewed editorially before publication. Responsibility for the content lies with the person named above. The procedure is set out in full under AI transparency.
Copyright and sources
Every text on this site is written from scratch. No third-party texts are taken over. Research sources are listed individually at the end of every content page; where a primary source exists — for technical subjects, as a rule an RFC — that is the one given.
All illustrations and diagrams are our own. No third-party images are included, neither embedded nor loaded from external servers.
Should an infringement of copyright nevertheless be present despite this care, please let us know through one of the contact routes above. The content complained of will then be examined immediately and removed if necessary.
Liability for content
The content of this site has been produced with care. No warranty can be given, however, for its accuracy, completeness or currency. Every content page carries the date it was last reviewed; the technical procedures described, and deliverability practice in particular, change continuously.
Liability for links
This site links to external sources, predominantly to technical specifications. We have no influence over their content; their providers alone are responsible for it. At the time of linking, the pages were free of recognisable legal violations. Should infringements come to our attention, the links concerned will be removed.
Applicable law
German law applies to this site and to all contacts established through it, including the directly applicable provisions of European Union law. This does not affect rights that consumers hold mandatorily under the law of their habitual residence.
Consumer dispute resolution
We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration body. Since no contracts are concluded through this site, no such dispute can arise.
