lines w/o backslashes at the end of each line or it's your MUA?

Did you really spit domainlist on few lines w/o backslashes at the
end of each line or it's your MUA?

^^^^^^^^^^^^^^^^^^ - try change it to something like:
host_lookup = !192.168.0.0/24: !192.168.1.0/24

^^^^^^^^^^^^^^^^^^^^^^^^^^^^ you can freely set it to 0s


> sender_unqualified_hosts = baby.espersunited.com :
^^^^^^^^^^^^^^^^^^^^^^^^^^ - usually you don't need this in case of
correct MUA settings.

^^^^^^^^^^^^^^^^^^ - are you sure you really need this in your case?
:)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - this does not work as expected. Use
something like 'require verify = recipient/callout=60s,defer_ok'.

Worth to set message size limit here for spam checking.

Why do you check message for spam twice? %)

See above.

of the reasons why I like Exim very much :)
