Hi Marc,
Something doesn't look quite right with your primary network interface
"eth0" versus your alias interface "eth0:0" ...
As eth0:0 looks like it's intended to be an alias of eth0 but with a
different IP address, but they have different netmasks and broadcast
addresses which looks odd to me ...I would expect them to have the same
netmask and the broadcast address if they are aliases on the same
network segment.
Is it possible that you have asymmetric traffic between oddly configured
interfaces?
Regards
Mike

After upgrading to 4.98 on a new server (don't know if it's the new exim

The problem is if I run exim in debug mode and check it myself, it works, so
callouts
only fail sometimes and I don't know how why or how to debug further.
I picked an Email that was in my reject pile, and callout is working fine, in
this case
it's getting a timeout which is fine, but that causes a callout failure
which is working as intended and not
T=remote_smtp Cannot assign requested address
The address is an ethernet alias, it's stable:

Logs showing when things work, below. Any idea how I can capture this better
or what could be
going wrong?
Mmmh, I had to remove the logs from the Email because the exim list
server was rejecting this Email as spam :-/

hopefully it'll be better like this.
Thanks,
Marc
