Hello, i've configured exim4 on a sarge system to perform authentication 
with the smarthost used to relay all emails it processes.

I put username and password in passwd.client this way (fake data obviously):

*:theuser at thedomain.eu:thepassword

all is working fine until i switch the default gateway in order to route 
traffic on a different dsl provider. it seems absurd to me, it's a 
matter of route add/del.

after changing the routing, smtp authentication fails regularly.
Please note that i am not using the provider smtp server as smarthost. 
I'm using an independent one not related to any provider.

exim4 -d+all marcopar at inwind.it

and i saved all the huge log here:

i really don't understand what's going on. it seems that exim does not 
send credentials when the traffic is routed via the new provider.

I've already tried to tweak exim4.conf.template, although i do not know 
the language in which is written, to avoid passwd.client parsing and 
forcing the data to be used and that way works so i think it's a script
