Thx Gordon. I will give them an earful! From: users [mailto:users-bounces(a)exim4u.org] On Behalf Of Gordon Dickens Sent: Tuesday, July 12, 2016 5:03 AM To: Exim4U General Discussion Subject: Re: [Exim4U] help with DEFER errors Hi Helmut, For item 1, your server is not successfully completing the reverse dns lookup of your host. With Exim4U 3.1.0, its on line 63 in exim.conf as follows: MY_IP = ${lookup dnsdb{a=$smtp_active_hostname}} This most likely is happening because your ISP's name servers are temporarily unavailable. If this happens alot then you should complain loudly to the ISP that hosts your IP address. If this problem persists often on an installation which is ***not*** using multi-ip then you can hard code your IP address into this statement to avoid the reverse lookup but that is merely an industrial strength band aid. Your ISP should get an earful about their servers that perform reverse lookups being unavailable. I have seen this before but it is generally very rare with most ISP hosting companies. For item 2, I have no idea what is going on. I would need more info and log data, etc. to proffer a guess. Gordon On 07/11/2016 03:47 PM, Helmut Fritz wrote: Guys, 1.

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.
