Jon, here's the last reply (from Thomas N) when this happened to someone else - see if it works for you:
[quote]Just guessing: perhaps, MIME-encoding was not turned on. It can be
turned on at "Tools" | "Options" | "Outgoing mail" | "Messages and
replies" -> "Use MIME features - ON". As far as I know, that option
can be set for each identity separately, so you had better check it for
all identites just to be sure.
When writing a message, you can toggle the MIME-option for the
particular message. At the "Special"-tab of the Message Editor window,
you can find the option "Use MIME features in this message for
Internet/local mail".
It is highly recommended to turn MIME on for all messages sent. I suggest that the first option I have mentioned is turned on for all identities.
If you want to know about MIME, the Wikipedia-entry at http://en.wikipedia.org/wiki/MIME may be a point to start from.[/quote]
