Message type

This condition lets you filter messages based on their type. You can choose from:

• New – Original messages that aren't replies or forwards
• Reply – Messages that are replies to previous emails
• Forward – Messages that have been forwarded
• Reply or Forward – Messages that are either replies or forwards

How it works

The application automatically detects the message type by checking:

• Reply messages – Subject line starts with Re: and contains reply information in the In-Reply-To message header
• Forward messages – Subject line starts with Fw: or Fwd: and contains forward information in the In-Reply-To message header
• New messages – Everything else that isn't a reply or forward

This makes it easy to create rules that handle different types of messages separately. For example, you might want to process new customer inquiries differently than forwarded reports.
