Well worth checking the transport layer (TCP).

I recently had an issue where my boss suddenly lost the ability to send
mail to our corporate gateway for relay from home. He got the same
message ("SMTP data timeout (message abandoned)") you quoted above.

Turns out, his network provider suddenly started filtering SMTP
connections to foreign hosts at the DATA command!

In my experience, it's worthless looking at Exim once you've seen that
error message -- your problem lies lower down.

Ciao,
