Check a message's details and headers
When you need to know exactly where a message came from, or support asks you for its headers, open the message’s details.
Open message details
- Open the message.
- In the message’s More menu, select Message details.
The window shows the sender, the To, Cc, and Bcc recipients the message carried, the address the message arrived on, the date, the subject, the message ID, the size, and how the message was encrypted. The encryption line reads End-to-end encrypted for mail that stays inside Aster, and Protected in Transit for mail that came from or went to another provider.
Copy or download the headers
In Message details, find Message headers, and then:
- To put the headers on your clipboard, select Copy.
- To save them as a file, select Download.
Some messages have no raw headers stored, and the window says so.
Send the headers when support or another provider asks why a message was delayed, rejected, or marked as spam.
Read the original source
To see the message exactly as it arrived, open the More menu, and select View source. The source view shows the raw message, and you can wrap or unwrap long lines and copy the whole thing. To close it, select Hide source.
Copy the message ID
A message ID identifies one message across providers. In the More menu, select Copy message ID. Support uses it to trace a specific delivery.
Print a message
In the More menu, select Print, and then use your system print dialog. To save a copy as a file, choose your system’s print-to-PDF option.
