The final timeout default value is 10 minutes.
The original poster said that "customers were receiving multiple
copies". However, I don't think we know whether this is because his Exim
is *receiving* the message multiple times, or *sending* the message
multiple times.
If it's timing out when receiving, the relevant option is
smtp_receive_timeout, defaulting to 5 minutes.
