Better e-mail quality by using SPF

/ Common

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.

Malicious phishing mails on the way

/ Common, Domains @en


Currently many domain owners are receiving faked e-mails informing about an alleged suspension of their domain. These mails are looking authentic, because

  • as sender deLink or another, really existing registrars is indicated
  • the e-mail adress of the recipient is correct
  • the personal name is correct
  • the domain really belongs to the recipient

Obviously the data was grabbed from the public domain whois. The content of the e-mail is similar to this:

Dear John Doe,

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.

These e-mails are FAKED.

If you click the proposed link, you will very probably get a trojan onto your device. In case of doubt please forward the e-mail to us, we will analyze it and give you a feedback.

US Dollar forces price adjustment

/ Common, Domains @en

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

/ Hosting @en


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

/ Domains @en, Domains @en

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

/ Domains @en

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

/ Common

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 for .de Domains

/ Domains @en

Have you already been close to a heart attack after deleting a .de domain accidentally? Until now .de domains were deleted immediately and irrevocably as soon as the request was forwarded to DENIC. And rather often interesting domains were registered by others only minutes later.

denic-eg_logo Now we are done with that: DENIC has introduced a Redemption Grace Period. Since 03.12.2013 the previous domain owner – and the previous domain owner only – has a time limit of 30 days to regain the domain by means of a RESTORE.

We appreciate this change of the regulations – domain grabbers presumably less.

Detailed information is availabe here at DENIC.

Are they really coming now?

/ Domains @en

After years of many announcements and even more postponements now the rumours are not ignorable any longer. The sunrise phases of the first newgTLD could start in 2013. On top of the priority list of ICANN there are (besides several endings in IDN spelling):

  • PLAY
  • DOG
  • FOOD
  • RUHR
  • BUY
  • ARTE

donutsThe registry Donuts Inc. estimates that the 60 day sunrise for some of these Domains could be opened at the end of October 2013 – prices, terms and conditions remain unpublished, however.

Did you already apply for a validation of your trade mark at the TMCH? This is the prerequisite to participate during sunrise for each and every new gTLD!


Until today 100% of all applications submitted via deLink have been approved by the TMCH. The reason might be the thorough precheck we are doing with your application documents. How you can submit your application via deLink very easily is described in detail here.

You still have no idea, which of the new gTLD might be important for you? Check here – we have categorized interesting endings. Take advantage of the research we did for you!
