Changing data center
The following content is no longer up to date. It refers to the period between 2018 and 2019. - Klicken Sie auf "Expand" bzw. "Ausklappen", um zu erweitern Haufe is changing its data center provider (Germany in 2019, Switzerland successfully finished in 2018). As a customer, you have already been informed of this, and referred to the following website which contains all the important details, questions and answers: https://customer.umantis.com/information/changing-data-center
Below, you will find the settings/configuration guidelines required for the change. Please note that some of these only apply to specific customer environments and are therefore not relevant for all customers. If certain settings have to be configured (before or after the data center change), you will be explicitly informed in advance.
Customer-specific URL
If you are using a customer-specific URL, certain adjustments must be made before the change. You have been or will be directly contacted and supported by a Customer Service specialist.
Mail relay
In order to ensure a smooth transition and continued full functionality of the Haufe solution, customers who are using a mail relay must review their mail relay settings. To do this, please take note of the following information:
Mail relay — What is it?
- Customer environments with a correctly configured mail relay allow our applications to send customer-specific emails through mail relay servers (belonging to the customers). To prevent misuse, such access is authorized. For these customer environments, authorization is based on the IP addresses of the e-mail senders, i.e. the Haufe mail servers. The authorized addresses are compiled in a "whitelist" on the mail relay server. If these entries are not in place, the Haufe emails will be rejected.
When do I have to make which settings?
- Before the data center change, you must add the server names of the two mail servers at the new data center (Germany: Frankfurt and Switzerland: Zurich) and the backup data center (Germany: Rüsselsheim and Switzerland: Geeneva) to the whitelist for the mail relay server:
| Germany | Switzerland |
|---|---|
| mail01.de.umantis.com | mail01.umantis.com |
| mail02.de.umantis.com | mail02.umantis.com |
| mail03.de.umantis.com | mail03.umantis.com |
| After the successful relocation of your customer solution to the new data center, the previously valid IP addresses (213.95.13.132 and 213.95.13.133) should be removed from the whitelist. | After the successful relocation of your customer solution to the new data center, the previously valid IP addresses (31.11.29.203 and 31.11.29.204) should be removed from the whitelist. |
Who can configure these settings?
- These settings are configured by you, the responsible staff members in your IT department, or the staff in charge of the mail server. The responsible person is informed of the customer-specific email domain and the name of the server that is used as the mail relay. We will send you this information (email domain and server name) via email.
How can I check whether the settings are correct?
- We (at Haufe) can only check the correctness of the settings after the customer environment has been moved, i.e. only when emails are sent through the mail servers at the new data center. However, if the customer has limited the sending of mail in such a way that Haufe receives no notification, then Haufe must depend on the customer’s reaction.
SPF entry
If you have set up an SPF entry, you must check it before the move. The entry should comply with our standard, which is described on the following page: SPF entry
IP address
Normally, no modifications need to be made unless you have configured specific settings. Because these are local settings that we cannot access, we cannot determine whether you have configured specific settings or not. For this reason, all customers receive an email communication that contains a link to a website. This website can only be opened if no specific IPs are stored on your system. Customers who cannot open this page should contact us immediately to obtain new IPs for the primary and secondary data center.
Contact
We have set up a central email address to which you can send any questions you may have about the data center change: hostingcenter_questions@haufe.com
