Miscommunication caused by poor phrasing on my part, sorry.
You reported on having two autoresponders responding to each other.
If you use "to = $sender_address", then you won't reply to a bounce,
because the bounce will have an empty sender.
Now, if the other auto-responder is using something other than the empty
sender, then that would explain it. And for that many responses, the
sender must have been varying.
The "exim_dumpdb" utility should let you look at the once DB; I suspect
something like BATV or VERP addressing from the other auto-responder,
which is ... unfortunate. Neither of those should be changing the empty
envelope sender, but buggy configurations are not unheard of.
You should really be using a senders filter on auto-responders, so you
could add more to that.
Eg, config.samples/C006 includes:
senders = !^.*-requ...@.* : !^owner...@.* : !^postmas...@.* : \
! ^listmas...@.* : !^mailer-dae...@.*
You probably want to build on that.
Probably also:
condition = ${if and{\
{!def:h_Auto-Submitted:}\
{!def:h_Precedence:}\
{!def:h_List-Id:}\
}}
to try to filter out some mailing-lists, auto-submitted stuff, etc.
If you have spam-scanning which inserts a header with a spam-score,
probably also worth not auto-responding to stuff which you consider
spam.
