deLink presents a new corporate design

deLink GmbH has been online for 20 years now. It is time for a change! For the first time in our company history we are implementing an extensive relaunch of our corporate design. We are happy to present our brand new logo within the framework of our edited blog design: 

Besides a newly designed lettering, our new slogan „we build solutions.“ will from now on be integral part of our communication. Step by step further areas and documents will be adapted both visually and contentwise due to the extensive transformation phase we are looking forward to.

The new look and feel initiates a new era in our company during which we continue to offer you the highest quality and performance of our products and services next to innovations – as before!

Best regards from Hamburg

Better e-mail quality by using SPF

What can you do to prevent other people from sending spam e-mails using your e-mail address as sender address?

sender_address_sampleThe answer is: Nothing, regrettably. In the same way as you cannot prevent other people writing your address onto a paper envelope and post the letter.

But: You can do something in order to help recipients to reject mails, which were not really sent by you! One useful method if SPF (Sender policy framework). Summarized SPF works like this: You add some information to your domain defining which mail servers you want to authorize as legal sources for your e-mails. The recipient can evaluate this information and reject e-mails or mark them as spam, which have your sender address but were not sent from mail servers authorized by you.

Well, the recipient may use this information, he is not obliged to do so. But an increasing number of recipients use this method and reject e-mails, which were sent from other mail servers than those authorized by you.

How to enter SPF information for your domain? Very simple:

  1. Log in at using your customer login data
  2. Go to DOMAINS -> Manage and click the DNS button next to your domain
  3. Enter the following data at Add new subdomain/service

Subdomain/Service: – leave this field empty –
Type: Select TXT
TTL: – leave this field empty –
Target: v=spf1 -allspf_enter_en

To finish click Add and then Save changes. Approximately 10 minutes later the SPF record for your domain will become public, and the method starts to work.

Please note!

The above entry is correct in case you are sending e-mails with your domain as sender address solely via the deLink mail system. If you are sending e-mails via other systems as well (e.g. a local mail server, via a newsletter provider) you have to add these mail servers to the SPF record.

Bösartige Phishing-Mails im Umlauf


Aktuell erhalten viele Domaininhaber gefälschte Mails, die über eine angebliche Sperrung Ihrer Domain wegen Missbrauchs informieren. Die Mails sehen echt aus, weil

  • als Absender deLink oder andere, tatsächlich existierende Registrare angegeben sind
  • die Emailadresse des Empfängers stimmt
  • die persönliche Anrede stimmt
  • die Domain dem Empfänger wirklich gehört

Die Daten sind anscheinend aus den öffentlichen Whois-Informationen der Domain abgegriffen worden. Der Text der Mail lautet in etwa

Dear Hans Mustermann,

The Domain Name have been suspended for violation of the deLink GmbH Abuse Policy.

Multiple warnings were sent by deLink GmbH Spam and Abuse Department to give you an opportunity to address the complaints we have received.

We did not receive a reply from you to these email warnings so we then attempted to contact you via telephone.

We had no choice but to suspend your domain name when you did not respond to our attempts to contact you.

Click here and download a copy of complaints we have received.

Diese Mails sind GEFÄLSCHT.

Wenn Sie auf den angegebenen Link klicken, laden Sie sich mit hoher Wahrscheinlichkeit einen Trojaner auf Ihr Gerät. Wenn Sie im Zweifel sind, leiten Sie uns bitte die Mail weiter, wir untersuchen sie und geben Ihnen eine Rückmeldung.

US Dollar forces price adjustment

DollarEUROSince many months the value of the EURO has been losing against the US Dollar, dramatically in the last few weeks. Most domain registries charge their fees in US Dollar. We did not forward the recent price increases by VeriSign and other registries to our customers.

But now the exchange rates are forcing us to increase the prices for several TLDs which are charged in US Dollar or GBP, coming into effect at the 1st of February 2015. The increase applies mostly to the higher discount rates and is kept at the possible minimum. Each customer will receive an individual e-mail with an exact listing of all changes concerning him.

The good news: The prices for several TLDs (where registries charge in EURO) will be reduced at the same time!

Shellshock at deLink


In 1985 the UNIX shell bash, developed by Brian Fox, replaced the commonly used Bourne shell at most systems. Since then it had a security leak, which could be used to attack systems and get extensive control. This leak was not discovered until last week. The first information about this leak – named shellshock – reached deLink at the 24.09.2014. Due to the nature of the issue every LINUX system at deLink was concerned – Debian as well as CentOS or SUSE.

Already the next morning we had patched all critical systems.

Immediately after more severe leaks were discovered in bash, so that all servers had to be patched again. Sunday, the 28.09.2014, the second row of patches had been applied and tested at all critical systems, hosting servers, managed servers and mail servers at deLink. All customers managing their own servers had been informed and given a guide how to secure their servers.

Careful investigation of all servers showed no trace that the leaks had been used for attacks.


Phishing e-mails addressed to domain owners

Often disturbed customers, who received ominuos e-mails concerning their domains registered with deLink, ask us for advice.

  • someone wants to register my domain and my “Internet Keyword” what shall I do?
  • someone sent an urgent payment reminder for my domain, have I got to pay?

When you receive e-mails of this kind, please be very cautious! Of course deLink will remind you before your domain expires and tell you whether you have to renew it manually or whether it will be renewd automatically (which is the default method). But there are some very typical methods used to drag the money out of the pockets of domain owners.

spam_delinkVery popular: You get an e-mail – allegedly from an internet provider, in most cases from China, but from Hongkong or Switzerland somtimes, too. You are informed that a company, which is totally unknown to you, has requested registration of your domain or your “Internet Keyword”. But it was detected that this request collides with your interest. You should answer asap regading this issue.

What does that mean? First of all the story about an alien company requesting your domain is completely fictional in most cases. And there is no such thing as an “Internet Keyword” which could be taken from your. The intention is to put you under pressure!

What is the purpose? The sender tries to induce you to register additional domains with different endings and – under pressure – pay exorbitant prices and accept incredible conditions. We have witnessed cases where a customer had to pay several thousand US dollars for just three domains. As soon as you have signed an order fax it will be extremely difficult to escape that trap!

What if you do not react? According to our experience – nothing at all. (If you really want to register the domains which were offered, you can do so via your preferred provider – at normal prices and conditions.)


Serach Engine Submission OfferAnother method method suggest that a domain fee has to be paid – urgently. If you look closer you will find that the payment asked for is not for a domain renewal, but for a search engine submission. The letter is just an offer, not an invoice, though it looks very much like a domain renewal invoice.

Very suggestive is a line e.g. WWW.DELINK.INFO will expire on DECEMBER 03,2013 – Act today!

But it is only the search engine offer, which will expire – not your domain!

Already more than 20 new gTLD in Sunrise

Currently in sunrise among others are already


If you already had your trademark validated by the TMCH, you may now request the corresponding domains. If not, it is high time to place an order for validation!


As a second choice you may request domains without having a validated trademark in the land rush periods of the relevant TLDs – preferred, but rather expensive.

Your last chance to get the desired domains is submission to the going public. It is first come first served then – thus a matter of luck.

Take a look at our list of the most interesting new gTLD – sorted by categories, start date of sunrise, landrush or going public, to get an overview.

Encrypted e-mail transmission

Everyone is talking about it: Who can read which of all the data transmitted via internet?

If you manage your e-mails via deLink you can make it a lot more difficult for unwanted eavesdroppers to read your e-mails: Use encrypted transmission from and to the deLink mail system!

keysThe mail servers at deLink allow encrypted transmission from today. You have the choice – if you want to apply enhanced security, you only have to tell your e-mail client  (OutLook, Thunderbird, MacMail … whatever you use) to do so: Replace the names of your incoming e-mail servers (POP3, IMAP) and outgoing e-mail server (SMTP) as follows:

– until now mail.<mydomain> (<mydomain> to be replaced by your individual domain name)
– new

and activate encryption in your e-mail client. Please refer to the e-mail clients documentation to find out how to do this.

Webmail and e-mail administration can be processed encrypted as well.  Just use for e-mail administration for webmail

You will be forwarded to a secure connection. Your login data for e-mail client, mail administration and webmail remain unchanged.

Redemption Period bei .de-Domains

Haben Sie auch schon einmal fast einen Herzstillstand gehabt, weil Sie versehentlich eine wichtige .de-Domain gelöscht haben? Bisher waren .de-Domains sofort und unwiderruflich weg, wenn der Auftrag bei der DENIC einging. Und interessante Domains waren häufig Minuten später wieder registriert – von wem auch immer.

denic-eg_logoDamit ist es nun vorbei: Die DENIC hat eine Redemption Grace Period eingeführt. Ab dem 03.12.2013 gilt: Wenn eine .de-Domain gelöscht wurde, hat der bisherige Inhaber – und nur dieser – eine Frist von 30 Tagen, um sie mit einem RESTORE wieder zu reaktivieren.

Wir finden diese Änderung gut – Domaingrabber vermutlich weniger.

Ausführliche Informationen dazu finden Sie hier bei der DENIC.
