Bug#631457: exim4-daemon-heavy: max_rcpt expires connections early

[Jasen Betts]

Package: exim4-daemon-heavy
Version: 4.72-6
Severity: normal


exim should keep the connection until connection_max_messages 
have been sent however it seems to stop after max_rcpt instead


to reproduce:

add the follwing global setting:

 remote_max_parallel = 1

add the following settings to the remote_smtp: transport

 max_rcpt=1
 connection_max_messages = 500

and then send a single email to multiple recipients at any remote domain

exim discards the connection and opens a new one between each email,
ignoring the setting connection_max_messages = 500
