Settings for email clients

For all email mailboxes managed by us, an automatic configuration is available.
All common email clients, such as Mozilla Thunderbird or Microsoft Outlook, can automatically find the correct server settings by simply entering the email address. Manual configuration is usually not necessary.

If you require or prefer a manual configuration, you can retrieve the necessary settings at any time as follows:

Open the website corresponding to your email address: https://autoconfig.your-email-domain.tld.
Example: Your email address is example@crymg.de. Then the address to open would be https://autoconfig.crymg.de.

On this page, you’ll find all the information needed to configure your email client.
Users of iOS can also download a profile there, which makes setup on iOS devices straightforward.

Spam and virus protection

Our email gateways perform comprehensive checks to actively protect against spam, viruses, and phishing.
Different rules may apply to incoming and outgoing emails.

Spam protection

All emails are automatically evaluated by various mechanisms. Points are assigned and a spam score is calculated.
Based on this spam score, emails are classified as follows and may be blocked accordingly.

• Spam score below 3.0: Emails are delivered normally.
• Spam score from 3.0 and below 7.0: Emails are delivered to the mailbox’s Junk folder.
• Spam score from 7.0 and below 15.0: Emails are not delivered directly but moved to the spam quarantine (see below).
• Spam score from 15.0: Emails are blocked directly by the email gateways and the sender is usually informed that the email could not be delivered.

Outgoing emails are blocked starting at a spam score of 3.0 and the sender is notified. This relatively low threshold is intended to prevent emails from being rejected on the recipient’s side and thus ensure deliverability. It also actively prevents real spam from being sent through our systems.

Spam quarantine

For emails that have been moved to the spam quarantine, the recipient automatically receives a daily spam report (when new emails are present).
This report contains the sender and subject of the quarantined emails as well as links to perform actions on those emails.

The report also includes a personal link to the spam quarantine web interface, where the user can manage all current emails in their spam quarantine. In this web interface, a whitelist and a blacklist can also be maintained, allowing personal settings for specific senders.

Emails in the spam quarantine are automatically deleted after 14 days.

Training spam and ham

Through the automated evaluation of spam and ham (not spam), our systems continuously improve in handling the current volume of spam.

Additionally, you can actively train spam by moving spam emails that were not recognized as such to the Junk folder of your mailbox. Emails that were incorrectly recognized as spam can be moved out of the Junk folder (e.g., back to the inbox).
Our system registers this moving of emails in the background and automatically learns the affected messages as spam or ham.

Don’t worry: If you accidentally moved an email and then move it back, this will also be detected and the classification of the affected email will be corrected automatically.

Virus protection

Emails in which viruses or phishing attempts are detected are completely blocked by our system.
These emails are moved to a quarantine, and we receive a notification so that we can carry out a manual review if necessary.

If a virus is found in an outgoing email, the sender is also notified and the email is not delivered.

Blocked attachment types

Some types of attachments are considered potentially dangerous and are therefore automatically removed from emails by our system.
A notice is inserted into the email informing that attachments have been removed.

Blocked attachment types primarily include executable files (cmd, exe, java, js, vbs, …) as well as certain office documents with potentially dangerous macros.

Alias email addresses

Alias email addresses can be used so that a mailbox can be reached via multiple addresses and can send emails from multiple addresses.

We offer two types of alias addresses.

Fixed alias addresses

Fixed alias addresses must be created once, after which the alias address can be used like the primary address for sending and receiving.

You don’t have to do anything for receiving emails on a configured alias address. This works completely automatically.

To send emails using an alias address, you must configure your email client accordingly. In Mozilla Thunderbird, for example, this is done in the account settings under Other identities.
Please note that our servers only accept emails from senders that were set up as an alias in advance.

Example: example2@crymg.de is set up as an alias for example@crymg.de. All emails to these two addresses end up in the mailbox of example@crymg.de, and both addresses can be used for sending.

Auto-alias addresses

In contrast to fixed alias addresses, nothing needs to be set up for the auto-alias function. It simply works with any number of auto-alias addresses; however, these cannot be used for sending emails.

An auto-alias always begins with the front part of the regular email address (i.e., the part before the @), followed by a + or - sign and any combination of letters and numbers, and ends with the regular back part of the email address (everything from the @ onward).

All emails to an auto-alias address end up in the mailbox of the corresponding primary address. The alias part is retained, so you can configure your own filter rules based on it.

Example: For the mailbox example@crymg.de, you can also use example-test@crymg.de or example+great@crymg.de without any further setup.

A combination of fixed and auto-alias addresses is also possible.

Using POP3

Using POP3 is disabled by default and IMAP should be used preferably.

If you need POP3 for your email mailbox, please contact our Support.

Email archiving

With our email archiving, all incoming and outgoing emails are automatically stored in the archive for mailboxes with archiving enabled.

Each customer has a separate instance of the archiving software and receives a personal link from us to a website through which the archive can be accessed. On this website, a user can log in with valid email credentials of an associated email mailbox and view their archived emails there.

If necessary, individual emails can be restored from the archive to your own email mailbox at any time.

Archiving is performed for 11 years from the receipt of the respective email. Early deletion of individual emails from the archive is not possible.

Access for auditors

Our archiving software provides auditor accounts through which specific (including external) users can be granted read-only access to all emails in the archive.

If you require an auditor account, please contact our Support.
These accounts should always be handled with special care and be time-limited.

Export and import in the archive

Through the archive’s web interface, you can export individual or multiple emails from the archive at any time on your own.

For an export of all emails or a bulk import of emails, please contact our Support.

Archive storage space

Because emails are archived for such a long period, this can require a considerable amount of storage space, and the used storage will continue to grow over the years.

We therefore monitor the storage space available to you and will inform you in good time as soon as it is at risk of becoming scarce.
In this case, you have the option of purchasing additional storage space from us.
