Sorry, I didn't see this mail until now.

The 'easiest' thing to do is to accept the message if it's going to take over 30 seconds to process, and generate a 'bounce' later if necessary - but I don't like that because of faked sender addresses.

Excellent plan.

Tweak the timeout so 99% of the rejections are in the SMTP session and less than 1% using bounces, and you'll be fine.

I've heard good things about delays of 36 and 46 seconds. To my mind, both seem a little long, but people I know have had good experience with those timeouts.
