Just a little feed back on what I have found::
by using the reject_hosts or reject_host_receipients, apparently if you use
full host names (without wildcards) this can slow down your queries.
Entries of the form
host1.domain.com
host2.domain.com
Will cause an extreme slowdown at initial SMTP connection,
BUT
*.domain.com
will not, and will give you the same results.
Also, *ost1.domain.com will help you get it under grips for the one host,
without slowing things down.
Apparently, if a fully qualified host name is given, exim will query dns to
get it's IP address for the comparison. If a wildcard is given, then only
the host name is compared with the text from the list. Wouldn't it be
better if a text comparison was done just like it appears to be done on
wild-card entries? OR maybe it should be an option that you can change.
Of course, there is always the obvious answer that I am wrong. But then, I
have complete confidence that I will be informed if I am.

Thanks,
Sometimes you just read the answer, and somehow don't read it. I just
needed someone to push me into working a little harder. Using "bh" option
found the problem. I have a rather long list of hosts not to accept, and it
was getting trapped checking the hosts out. I guess I need to clean up my
list.
(host_reject = /usr/exim/tables/host.reject)

and to all whom it may concern,
1) the answer is a FAQ entry
2) the answer is in the archives gazillion times
3) once you get a reply at least try it (alternatively, 'why do you
ask if you know if better anyway?')
4) don't top-post
additionally, i'd like to propose to add a specific "30 seconds"
literal to Q0026. it might help a bit (?).
