[exim] SMTP data timeout after upgrade from 4.30 to 4.43

Has the timeout setup or default values for timeouts changed between
Exim 4.30 and 4.43?

We are getting

2006-05-12 13:29:52 1FeVlM-0005ti-AC SMTP data timeout (message
abandoned) on connection from localhost (opel.procaptura.com) [127.0.0.1]

for some very large messages on a Exim 4.43 setup, and I think Exim 4.30
with exactly the same config file was quite happy to accept the same
messages.
