Preamble

• If you do not have a compatible offer or if you prefer a simplified configuration, refer to this other guide.
  • ⚠️ No support is provided regarding the Sieve language (refer to this documentation — also discover the role of the host).
• Unlike the sorting rules offered within software/email clients (Microsoft Outlook, Mozilla Thunderbird, Apple Mail...), these rules will act directly on the server of your mailboxes before even the IMAP connection.
• It is possible to import Sieve files via a button.
• By activating this mode, the existing standard rules will be kept but deactivated.
• The redirect command (allowing to forward an email to another address) is not allowed in scripts.
  • If you import a Sieve script from another host, make sure to remove this command.
  • To forward emails, use the assistant in Standard mode or the Redirections section of your Mail Service.

Access rules from the Infomaniak Web Mail app

Prerequisites

• Have permission to manage rules: if you had been invited to the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail) to manage your address, it is possible that the Mail Service manager has removed this right from their admin account.

To access the sorting filters for your Infomaniak mail:

1. Click here to access the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail).
2. Click on the Settings icon in the top right corner.
3. Check or select the email address concerned in the drop-down menu.
4. Click on Filters and rules:
   

Access rules from a Mail Service

To access the sorting filters for your Infomaniak mail:

1. Click here to access the management of your product on the Infomaniak Manager (need help?).
2. Click directly on the name assigned to the product concerned.
3. Click on the email address concerned in the table that appears.
4. Click on the Rules tab from the left sidebar (or top bar):

First example of advanced sorting

Here is a simple example of a command using this language:

require ["fileinto"];
if address :contains "from" "facebook.com" {
    fileinto "fb";
} elsif header :matches "List-Unsubscribe" "*" {
    fileinto "nl";
} else {
    keep;
}

Explanations:

1. Loading required extensions: use require ["fileinto"]; to indicate that you will use the fileinto function.
2. Filtering Facebook messages: use if address :contains "from" "facebook.com" to check if the sender's address contains "facebook.com"; if so, the message is filed in the "fb" folder with fileinto "fb";.
3. Filtering messages with an unsubscribe link: use elsif header :matches "List-Unsubscribe" "*" to check if the "List-Unsubscribe" header is present in the message; if so, the message is filed in the "nl" folder with fileinto "nl";.
4. Keeping other messages: use else { keep; } to keep all other messages that do not match the previous criteria.

Note:

• If you need to mention a subfolder, use the separator / (as in the second example), but it is not necessary to specify INBOX in your codes
• Make sure that the folders fb and nl already exist in your inbox; otherwise, the messages may not be sorted correctly
• The filter address :contains "from" "facebook.com" works correctly for addresses that contain "facebook.com" in the "from" field
• The filter header :matches "List-Unsubscribe" "*" checks only for the presence of the "List-Unsubscribe" header, not its content

Second example of advanced sorting

This code modifies the subject based on thesender (adds a prefix to the subject when an email passes the filter, for example):

require ["fileinto", "editheader", "variables", "regex"];
if address "sender" "owner-scientific-linux-devel at LISTSERV.FNAL.GOV" {
    if header :regex "subject" "((Re|Fwd): *)\\[SCIENTIFIC-LINUX-DEVEL\\] *(.*)" {
        deleteheader "Subject";
        addheader "Subject" "${1}${3}";
    } else {
        # Ajouter un préfixe si l'objet ne correspond pas déjà au modèle
        deleteheader "Subject";
        addheader "Subject" "[SL-Devel] ${1}";
    }
    fileinto "Mail List/SL-Devel";
}

Explanations:

1. Required extensions:
   1. fileinto: to file messages in folders.
   2. editheader: to modify email headers.
   3. variables: to use variables in expressions.
   4. regex: for regular expressions.
2. Sender condition:
   1. if address "sender" "owner-scientific-linux-devel at LISTSERV.FNAL.GOV": checks if the sender matches.
3. Subject condition:
   1. if header :regex "subject" "((Re|Fwd): *)\\[SCIENTIFIC-LINUX-DEVEL\\] *(.*)": checks if the subject matches the specified pattern.
   2. deleteheader "Subject"; and addheader "Subject" "${1}${3}";: deletes the existing subject and adds a new subject with the captured parts.
4. Add a prefix if the subject does not already match the pattern:
   1. addheader "Subject" "[SL-Devel] ${1}";: adds a "[SL-Devel]" prefix to the subject if it is not already present.
5. Message classification:
   1. fileinto "Mail List/SL-Devel";: classifies messages in the "Mail List/SL-Devel" folder.

Note:

• Make sure the folder "Mail List/SL-Devel" already exists in your inbox.
• Check that the script correctly modifies the email subject to add or adjust the prefix if necessary.
