Hello all
I'm puzzled about exim's re-use, or not, of an SMTP connection.
In my config file I have got inter alia:
-------------------------------------------------
# Main configuration to put everything to outside Demon NL on the queue
queue_smtp = true
queue_smtp_except = *.nl.demon.net
queue_run_max = 40
remote_max_parallel = 5
# ... non-standard logging
log_level = 4
log_received_recipients = true
log_received_sender = true
log_refused_recipients = true
log_smtp_confirmation = true
# ... a standard remote_smtp transport
remote_smtp:
driver = smtp
# ... and a domain-list router:
demon:
transport = remote_smtp
driver = domainlist
route_list = " \
kantoor.nl.demon.net kantoor.nl.demon.net byname; \
ftp.demon.nl ftp.demon.nl bydns_a; \
abroad.noc.nl.demon.net abroad.noc.nl.demon.net byname; \
demon.net internal.mail.demon.net byname "
-------------------------------------------------
Now in mainlog I see several messages for the same destination (same
username in fact) arriving within a short space of time and being
queued, then being flushed out at the next queue run: (lines folded
for clarity)

1998-06-15 19:10:48 End queue run: pid=25891
... but there isn't an asterisk to indicate a re-used SMTP connection,
even though they are all being routed (explicitly) to the same place.
Have I overlooked something?
