Cool.
I've been meaning to add this:

If you do header and envelope callbacks, you can disable them for bounces to
mailman lists (it is quite common for internal hosts to bounce with a non
reachable internal address). The idea is that you typically don't want non
bounceable Email, but you'd better accept bounces to mailman lists so that
you can unsubscribe the people who are bouncing.
The rcpt-to ACL should look something like this
# Accept bounces to lists even if callbacks or other checks would fail
warn message = X-WhitelistedRCPT-nohdrfromcallback: Yes
condition = ${if and {{match{$local_part}{.*-bounces\+.*}} {exists {MAILMAN_HOME/lists/${sg{$local_part}{(.*)-bounces\+.*}{\$1}}}}}{yes}{no}}
accept condition = ${if and {{match{$local_part}{.*-bounces\+.*}} {exists {MAILMAN_HOME/lists/${sg{$local_part}{(.*)-bounces\+.*}{\$1}}}}}{yes}{no}}
# Now, do basic address checking, that we forgo if the receipient is in a
# whilelist
deny hosts = !+localadds:!+host_disable_callback:*
sender_domains = !+envdomain_disable_callback:*
local_parts = !+noenvfromcallback
!verify = sender/callout=90s/check_postmaster
and the data ACL, like this:
deny hosts = !+localadds:!+host_disable_callback:*
!condition = $header_X-WhitelistedRCPT-nohdrfromcallback:
!condition = ${lookup{${domain:$header_from:}}lsearch{HDR_DOMAIN_DISABLE_CALLBACK} {yes}{no}}
!verify = header_sender/callout=90s/check_postmaster
# Thanks to the exim4.gooderror.diff patch, exim will return
# informative error messages. You can override that with a generic
# message though
#message = Header sender couldn't be verified
