Sorry about that, can supply raw samples via private/irc/jabber.

The two warning acl from last my comment were used in acl_smtp_data, so this To
comes from some remote client (it's MX server).

Yes, I use dynamic modules but I always build my own rpm package first, so
nothing is out of sync here. Old ones were uninstalled after upgrading my own
rpm exim package (This exim is used in pld-linux.org distro here).

Note that here the only censored thing is "xxx" domain.

But why some other things have influence on single acl entry?
warn message = Test2
condition = ${if match_address{${address:$rh_From:}}{${address:$rh_To:}}}
If I remove these two lines from acl_smtp_data then problem is gone. There
aren't any address lists used in it etc.
I looked into last 100 cases here and always $rh_To was in form:
"Undisclosed-Recipient:;"@???
Just tested this on my simple, laptop exim config with above 2 lines added in
