Frequently asked questions


How does user-managed filtering of e-mail work?

Domainnameshop offers user managed e-mail filters, giving you control of how your incoming email is organized and filtered.

Administration of e-mail filters is managed via webmail, but any rules and filters you create here, will work for all incoming e-mail regardless of whether you are using webmail or not.

To get started, log in to webmail with your e-mail username and password, and click your way to SettingsFilters (basic).

Adjust spamfilter threshold

Each e-mail received by Domainnameshop's e-mail servers will be processed by spam filters, which will label the message with a specific number (spam score). The higher the score is, the more likely it is that a message is undesirable, or spam.

If you receive a lot of spam, or if legitimate e-mail is delivered to your spam folder, you can easily adjust how aggressively the standard filter is, that is, how high the score must be before a message is considered spam.

If you are curious about what spam score a message got, you can see this in the message headers. In the webmail, you can click on MoreView source, and scroll down until you see X-Spam-Score, example:

X-Spam-Score: 3.8

A message with a spam score of 3.8 will be placed in the spam folder if you have chosen a low spam threshold (3), and in the inbox if you are using the default value (5).

Approved lists and blocklists

It is possible to specify approved lists or blocklists for senders. This overrides ordinary spam filtering, and ensures that e-mail from these senders are placed in your inbox (approved list), or spambox (blocklist).

You may find it useful to add known important senders in your approved list, to ensure that messages from these senders are not placed in your spam folder.

If you receive unwanted e-mail from a sender, you may add the sender's e-mail address to Blocked senders, ensuring that their messages are delivered to your spam folder instead of your inbox.

Organize incoming e-mail to folder

You may configure automatic organization of incoming e-mail to specific folders, based on a range of criteria, e.g.: subject, sender, recipient. As an example, you can ensure that all invoices from a specific sender will be placed in an Invoice folder:

Example: Automatically deliver e-mail from multiple sources to a specific folder

See below for a recipe for automatically organizing invoices from multiple invoicing sources to the same Invoice folder, similar to the above example.

  1. Before you can create this filter, you must create the target folder for the messages, otherwise the messages will be delivered to your inbox. To create a folder in webmail, go to: SettingsFolders, and click on Create in the upper right. Name the folder, and click on Save.
  2. Go to SettingsFilters (advanced) and click the create (plus sign) in the upper right to create a new rule. Name the filter, e.g. "Invoice filter". Ensure that the filter is enabled, and set Scope to matching any of the following rules.
  3. Under Actions, select Move message to and select the folder from the list to the right.
  4. Then, under Rules, you may now add filtering criteria. For instance, you may add known invoice senders by adding a rule for each sender, with From contains, and enter the sender's e-mail address. Create additional rules by clicking on the plus sign next to the rule:
  5. Finally, click on Save to save your filter. The filter will be active immediately, and will be applied to all incoming e-mail regardless of what software you use for reading. In the example above, all new e-mail from and will automatically be placed in the folder Invoices

Advanced: Editing filter rules (sieve)

Note! Customer support can not provide support for these kinds of filters.

Behind the scenes, Domainnameshop uses the programming language Sieve to define e-mail filters. Sieve has a lot of additional functions compared to the web interface.

To edit raw sieve filters for your e-mail account, click on ActionsEdit filter sets over the rule list within Filters (advanced).

If you have added e-mail addresses to the approved list or blocklist, you will see the raw rules here, as well as the rule handling automatic filtering of spam to the spam folder (spam threshold). You are free to modify and expand these rules, they only affect your account.

Note! If you modify, expand, or add rules this way, we recommend that you do not edit rules in the basic web interface, as this will most likely ruin your advanced rules.

Examples for functions requiring manual rule editing:

  • Automatic filtering based on date variables, e.g. monthly invoice folders: Invoices/2021/04, Invoices/2021/05
  • Automatic filtering of "plus" addresses to separate folders. If your e-mail address is you may register at e.g. Netflix with, and create a rule that automatically places e-mail for that address to the folder netflix. The folder name is dynamically determined based on the text following the plus sign.

    Here is a complete Sieve example:

    require ["variables","fileinto","subaddress","mailbox"];
    # rule:[Filter to detail folder]
    if address :detail :matches "to" "*"
           fileinto :create "detail/${1}";

For technical reasons, the following Sieve extensions are unavailable:

  • vacation
  • reject
  • ereject
  • notify
  • enotify

Additionally, it is not possible to forward e-mail (redirect) with sieve rules. Forwarding must be handled via e-mail administration on our website by the domain administrator.
