Before my patch, this timeout was 3600 seconds, and wasn't properly
enforced. The difficulty is setting a reasonable timeout timeout
for the connection during SMTP time. We noticed duplicate emails
being delivered when spamd took longer than the SMTP timeout (300
seconds) before my patch. 240 seconds is very close to 300 depending
on what other time consuming checks you perform after DATA (maybe
anti virus).

I have thought of that, but haven't had the time yet.
