Hi, In Mail preferences I have message font set to Verdana and in the 'Composing' pane I have ensured that messages are sent as Rich Text, and yet I have a persistent and frustrating problem with Mail.app failing to apply font formatting to outgoing messages. When composing new messages everything looks fine (i.e. text displays in Verdana), but Mail isn't applying the formatting to emails; looking at the raw source of sent messages, Mail seems to be sending Plain Text messages with no formatting applied: Code: Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v936) Further adding to my confusion, if I append a formatted signature (configured in Mail preferences) to messages, the signature IS correctly formatted (in Verdana, no less). In such situations, the raw message source shows: Code: --Apple-Mail-6-661070991 Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit [MESSAGE BODY TEXT] [SIGNATURE TEXT] --Apple-Mail-6-661070991 Content-Type: text/html; charset=US-ASCII Content-Transfer-Encoding: quoted-printable [FORMATTING] --Apple-Mail-6-661070991-- So it seems that Mail is not sending the message body content as Rich Text, despite having set this in Mail preferences. Mail is running on OS X 10.5.8 on a PowerMac G4. Any help is really appreciated, thanks.
