Guys, 1. I have a lot of these type of messages in my mainlog: H=(mx.sendinghost.com) [xxx.xxx.xxx.xxx] Warning: ACL "warn" statement skipped: condition test deferred: failed to expand ACL string "${lookup dnsdb{a=$smtp_active_hostname}}": lookup of "a=my.host.com" gave DEFER: I am trying to look through the configs to see if I can determine where and why I am getting these. Are they a cause for any real concer? What causes them and can it be recified? I am not running a multi-ip host, but do host multiple virtual domains. 2. I am not sure if it is related (I think not), but I also get messages that correspond with the sending host that is in some of the above messages but the emails do NOT seem to come through to the users mailbox. I (think I) do see the actual emails in the /var/spool/exim/scan directory though. The only thing I find in the logs is this message: 1b4BZC-0005p9-Ek H= mx.sendinghost.com [xxx.xxx.xxx.xxx] Warning: spam-score-int: 1 (/). spamreject: 990. Any help, ideas or thoughts would be welcome. I did a google search that did not seem to provide an useful help. Thx. Helmut P.S. not yet updated to latest release of exim4u.
