Thunderbird spellcheck niggle

[Sickboy]

After many years of meaning to change, I finally dumped Outlook and started using Thunderbird. It's fine except for one small niggle;

I have it set to spellcheck emails before sending which it does, but it seems to be checking everything in the message header as well. This obviously includes loads of things that aren't in any dictionary, so is there a way to stop it?

I don't know if you've gotten an answer yet; but I haven't used thunderbird for a while. you should be able to get an answer at the Thunderbird site.
