30.17 Message type filter
30.17.1 Overview ¶
The message type filter automatically detects which kind of mail is involved: regular email, newsletter, automatic reply, bounce notification, calendar invitation, read or meeting response, or spam. It is the solution for profiles that should target only certain mail types or exclude typical “noise mails”.
30.17.2 Available types ¶
| Type |
Matches |
| Normal |
Standard email without special marking |
| Read receipt |

| Delivery receipt / Bounce |

| Auto-reply |
Out-of-office or automatic reply |
| Calendar invitation |
Invitation to a meeting |
| Meeting response |
Response to a calendar invitation (accept, decline, update) |
| Newsletter |
Bulk mail with unsubscribe notice |
| Spam |
Marked as spam by the mail server |
30.17.3 Operators ¶
| Operator |
Description |
| equals |
Message is exactly of the specified type |
| does not equal |
Message is not of the specified type |
30.17.4 Detection ¶
The program inspects typical message characteristics (e.g. content type, mail server tags, multilingual subject line heuristics for out-of-office replies). If no special type is detected, the message counts as Normal. Spam overrides newsletter and auto-reply, so that a newsletter mail flagged as spam appears under “Spam”.
30.17.5 Use case ¶
Automatically move newsletters to archive
Message type equals Newsletter
Combined with the task Move email into a “Newsletter” folder, this reduces inbox volume without deleting newsletters.
30.17.6 Tip ¶
- Detection is not 100 % - mail servers handle markings differently. For misclassifications, the Result preview (see chapter 8.11) shows how the program has classified a sample message
