Not sure if it is related, but my /var/spool/exim/scan and /var/spool/exim/input directories have a lot of files in them.

Input: 2223 files

Scan: 2223 files

I am sure it is not a coincidence.  The queue is empty.  The files names definitely seem to correspond between the two directories.  All the files in inpur are –D files (I believe that means body, -H is header).  Interestingly there are n o corresponding –H header files in input.

I was notified of this issue by a client who has not received any emails from the below mentioned mx.sendinghost.com [xxx.xxx.xxx.xxx].

They do get a reject message on their end of:

Generating server: mx.sendinghost.com

client@hisdomain.com
#< #4.4.2 X-Proprietary; lost connection with my.host.com [xxx.xxx.xxx.xxx] while sending end of data -- message may be sent more than once> #SMTP#

I did run a:

exim -bh xxx.xxx.xxx.xxx

and it ends up at an ACCEPT.

Subject: help with DEFER errors

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
