New security certificate

Created on 23. February 2024, 11:35 | Category: Info

Dear Posteo customers,

We are updating our main security certificate. Security certificates are only valid for a specified time period and need to be renewed from time to time.

In most cases, you will not notice any change.
All current clients like Thunderbird or Outlook will automatically find the new certificate. You do not need to do anything. However, should your client display a certificate error during this changeover process, please restart your client. This should fix the error.

If you manage the trustworthiness of certificates manually, you can find the fingerprint for the new main certificate below. You can also find complete fingerprints for all certificates in our legal notice.

New fingerprint for the TLS security certificate for posteo.de:

Geotrust:
SHA256: AA:FC:E1:21:F4:15:14:E6:8D:09:ED:F4:87:EA:E6:1E:02:99:BC:9B:41:51:4C:FC:DC:BE:F5:E8:A5:60:9C:DD
SHA1: ED:87:9A:C6:E6:2E:72:82:42:AD:30:D9:05:38:30:34:7C:47:2F:24

Best regards,

Now available: posteo.com and additional Posteo domains

Created on 15. December 2023, 13:45 | Category: Info

Dear Posteo customers,

We are expanding our range of services: From now on, accounts can also be registered with the email domain @posteo.com. Additionally, we offer the domains @posteo.us, @posteo.ca, @posteo.uk, @posteo.ie, @posteo.es, @posteo.at, @posteo.ch, @posteo.nl, @posteo.be, and @posteo.lu.

#more#

Previously, accounts could only be registered with either @posteo.de or @posteo.net endings. Many of you have asked for these additional options.

If you prefer one of the new domains for your existing account, you can now rename it easily in the settings via “Email aliases”. Your previous address will then be converted into an alias, so that you can continue to receive emails to that address.
If necessary, you can find further information in our help section.

There are many other top-level domains (the address part after “@posteo.”) also available for Posteo email aliases, such as .me or .eu.

By the way: Your Posteo address can only be registered by you for the other Posteo domains. For example, if you have the address mymail@posteo.de, only you can register the address mymail@posteo.com.

Best regards,
Your Posteo Team

New at Posteo: Optional spam folder and spam log

Created on 17. October 2023, 17:20 | Category: Info

Dear Posteo customers,

We have released two new spam options. From now on, you can manage your mailbox with or without a spam folder – or use the spam log. The new options can be activated or deactivated in your account settings. Allow us to introduce them to you.

#more#

If you do not use a spam folder, emails that have been classified as spam are rejected and the sender is informed of this rejection. You save time in your daily routine as there is no spam folder that must be checked regularly and sorted through. Because from a legal point of view, emails in a spam folder are also generally considered as delivered. Additionally, your email address becomes considerably less enticing for spammers if their potentially dangerous digital trash is regularly rejected.

Attempts to reach out to someone are also often overlooked in spam folders or noticed much later. This is the reason why the Snoop Dogg song “Chai Tea with Heidi” almost didn’t exist because Heidi Klum overlooked an email sent by the rights holder, Rod Stewart, for almost two months in her spam folder. Email clients like Thunderbird, Outlook or smartphone apps may even automatically delete emails in spam folders after a short period of time. Therefore, please be sure to check the settings for deleting emails in your programs if you use a spam folder. Otherwise, communication could be lost. We do not delete emails from the spam folder.

Spam folder: Receive all spam emails

Whoever decides to use the optional spam folder can check there at any time which emails have been classified as spam by us. All spam emails will be delivered in this folder.

From a customer service perspective, we know that it is very uncommon for spam to be falsely classified and is mostly only suspected. If an expected email is missing, in most cases it turns out that either the email address was misspelled or the message was sent to another email address. Often the email in question arrives shortly thereafter. Sometimes customers have also activated a filter that immediately sorts incoming emails to subfolders or deletes them. Or they use external email clients that sort emails into their own spam folders. Sometimes, it’s just that the inbox has also been accidentally sorted differently – and incoming emails are not longer displayed as usual.

Please check the scenarios described above if you have activated the spam folder and suspect that an email has not been received. From a technical standpoint, you can be sure that we deliver all emails sent to your mailbox, even if they have been classified as spam.

Activating the spam folder can lead to your email address becoming considerably more attractive for spammers – and result in you receiving more spam. Therefore, you can also temporarily activate your spam folder as needed. For example, during a period where you are sending off job applications and want to be absolutely sure that nothing can go wrong under any circumstance or that something may need to be clarified first.

Steer a middle course with the spam log

Are you not interested in managing a spam folder but still want to know which emails are rejected? Then, as an alternative to the spam folder, you can activate our new spam log.

By doing so, potentially dangerous spam emails will continue to be rejected. We also document each rejection for you transparently in a spam log folder. The log contains details about the sender, date, time and subject (if applicable) of the rejected email and is created in real-time. Warning: Sender names are often falsified by spammers.

Should you suspect that an email has been incorrectly rejected, you can check the log and know with immediate certainty.

Be careful with spam

Regardless of whether you decide for or against a spam folder: Always be careful when dealing with suspicious emails. Never click on links or open attachments in such emails and never answer them. In general, legitimate senders do not request that you click on links and then enter login credentials or other data. For your security, images are not loaded in the spam folder and clicking on attachments and links is deactivated in the Posteo interface and our web app. If you move the email to another folder, contents can be loaded and clicked on as usual.

If a sense of urgency is suggested or pressure is exerted, it is often a clear indication of spam or phishing. This rule of thumb helps: Never give in to such harassment. If you are unsure, you can always first contact our free customer support. We can advise you how to deal with suspicious emails. There are also no dumb questions: Even IT professionals can become unnerved by well-made spam emails and will contact us. Our team always takes you seriously.

Best regards,
Your Posteo Team

New at Posteo: Many Colors and Dark Mode

Created on 20. April 2023, 16:45 | Category: Info

The new colors of Posteo

Dear Posteo customers,

Starting today, we will be gradually releasing new features for you: Just in time for the beginning of spring we are bringing some color to your mailbox – we are now offering our user interface in 10 new variants. Additional updates include dark mode as well as two levels of contrast.

Regardless if you prefer yellow, pink, red or neutral colors like beige, brown or blue: From now on, the color of the user interface can be adjusted in the settings. The selected color will be applied to all areas, such as the calendar, notes, the attachment browser or in the Posteo web app.

Each Color in Two Contrast Levels

It is also new that all color variations are now available in two contrast levels. If you regularly work several hours in front of a screen, a color and contrast selection tailored to their own needs can be much more pleasant. Please try it out!
The contrast toggle switch can be found in the settings directly above the color selection.

Dark Mode

Another update: Starting now, you can activate dark mode. The background will then be displayed darkened and the text brightened – in the color you have selected. dark mode is especially useful for reading emails in darker settings. Many people also consider this more pleasant on the eyes in general.

Additionally, you have the option to automatically control Light and dark mode based on your operating system settings: The Posteo interface will then adapt accordingly – also on smartphones using the web app.

There is a toggle switch for dark mode and auto dark mode directly above the color selection.

We will gradually release all new features over the next few weeks. As soon as they have been released for your account, you will find the new options in Preferences via “User Interface”. These features are available free of charge without any further action on your part.

Video and Help Guides

In our video, you will learn how to select your personally favorite color and contrast level – and how dark mode works. There are also versions of the video available in French and German.


You can find step-by-step guides in our help section here:

New security feature: The deletion notification

Created on 17. March 2023, 12:30 | Category: Info

Dear Posteo customers,

Perhaps you have already noticed that we have released a new feature: the deletion notification. The new security feature protects you from unnoticed data loss; for example, if you have accidentally deleted emails from your account. The new feature has proven to be successful in everyday use. That’s why we would now like to officially present the deletion notification in our blog.

#more#

It is not so uncommon for customers to accidentally delete emails or an entire folder. We would like to provide you with the best possible protection for such cases: Posteo has always offered a special service of creating daily security backups of all email accounts and storing them 7 days for you. If needed, we can then restore these backups for you free of charge.

We have developed the new deletion notification because on a daily basis it was sometimes not satisfactory for us when customers would notice too late – after more than 7 days – that they – or the programs and devices they use – accidentally deleted many emails. We were then no longer able to help them.

With the new deletion notification, this no longer happens. Our system automatically sends a notification via email as soon as the amount of emails in your account is reduced by at least 50 emails within the past 24 hours.
And we can already say that the new feature is a complete success. Meanwhile, almost all customers that accidentally deleted emails contact us in time so that we can restore their data from our security backups. We have been happy to see the positive and relieved responses – thank you for this.

Notice:

Posteo will never request in an email that you click on a link and enter data on a website. Even our deletion notifications are purely informative without such prompts. Have you received an email that appears untrustworthy? Contact our support team for an evaluation at: support@posteo.de

Unlocked cell phones, errors in local clients

The main reasons for accidentally deleting emails can be quickly listed:
Often customers report of “cleaning” gone wrong in their own account – or from smartphones that were not locked in a pocket or bag.

Deletions are more likely to go unnoticed when customers are unaware of deletion settings in their local email clients – such as in Apple Mail, Outlook or Thunderbird. Therefore, it’s generally worth it to check the deletion settings in external email programs. Also, when updating these email clients, errors can sometimes occur that cause emails to be deleted unexpectedly.

By the way, out of principle Posteo never deletes emails from your email account – not even if your storage quota has been filled. We often receive this question.

I received a deletion notification – what do I do now?

If you receive a deletion notification from us in the future, follow these steps:

If you intentionally deleted the emails, simply ignore the deletion notification.

If the messages were accidentally deleted, verify if apps or email clients on your devices are automatically deleting emails. Perhaps your email client (e.g. Apple Mail) automatically emptied the trash. This is sometimes set by default in some email clients. You can, however, change this setting retroactively if you do not want emails to be automatically deleted. For example, also check individual folders, such as the “Sent” folder or your archive.

We do not have any information whatsoever regarding which emails were specifically deleted. The deletion notification has been implemented in a privacy-friendly manner and is entirely generated from values when calculating storage space. We do not look into email accounts and we also do not log which emails were deleted.

Should you be missing emails that you still need and do not have your own backup, please request for us to restore a backup within the next 7 days. This can be done in your settings via “Restore emails”. The backup contains all of the data in your account before the time of deletion. Alternatively, you can request to restore a backup from our customer service via email.
If needed, you can also adjust the deletion settings in your external email client to prevent unwanted deletions in the future.

Adjusting or deactivating deletion notices

Another tip: You can specify in your settings via “Password and security” to receive a notification only when more emails are deleted. This setting is particularly useful for people who regularly delete a lot of emails. If you no longer wish to receive deletion notifications, you can also deactivate the feature there.

We also recommend regularly creating your own backups of all saved data.

Best regards,
Your Posteo Team
