Lotus Notes works to preserve fidelity of text styles when you send or receive Internet mail, but if you discover that styles are lost, you can optimize certain settings for messages from both Notes mail and Internet mail users.

Notes attempts to deliver your outgoing messages in the format preferred by the recipient. If Notes cannot determine the recipient's preference, Notes sends messages in the format specified in your current location document, which is MIME by default. Most Internet mail programs understand MIME and can display the text styles and pictures in your messages.

To preserve text styles and pictures in Internet mail you receive, make sure your Person document in the Domino directory has Keep in sender's format set as the Format preference for incoming mail. This preference is best when you receive mail from both Internet and Notes mail users.
Tip: When Keep in sender's format is selected, you can see the HTML source or a message you receive from the Internet by opening the message and clicking View > Show > Page Source. This is useful if
you want to see the complete header of a message to trace its origin and create a mail rule to filter messages from certain addresses.
