    Hello,

    Scenario:
    I have 3 production servers. All have the latest cpanel installed. All have Freebsd 5.4 with exim 4.62.0

    My company email account resides on server 3, where I get sever log emails from all servers.

    -> root@hostname.server2.com sends log emails to my email-id@domain.com (on server 3) without any problems; server logs, new account information, etc etc. server 3 receives and delivers it to my mailbox (local delivery on server3).

    But!!

    -> When

    1) root@hostname.server1.com or
    2) cpanel@hostname.server1.com

    sends the same server logs, new account notifications etc etc for server 1 to my email address, it gets a 'sender verify failed' from server 3.

    Server 3 accepts email just fine from server 2, but in the same situation, doesn't accept mail from server 1.

    Server 1 was recently re-built. It has no accounts on it. I had this problem, when I created a new account and checked the mail server queue. All mails from server 1 were frozen in queue because server 3 was not accepting them.

    Need an insight and help! into the matter

    sounds like
    hostname.server1.com does not have an A entry for the DNS I would chaeck that


    and if you turn off sender verify in your exim.conf on server 3 it will deliver

    Update on the scenario

    DNS is setup properly..

    Note: Hostnames, domain names are masked in the scenario.

    All hostnames;

    - hostname.server1.com
    - hostname.server2.com
    - hostname.server3.com

    are proper FQDNs' in their respective zone files.

    -> The domain name => server1.com is completely (website, ftp, mx, etc etc) hosted on server2 at the moment.

    -> cp.server1.com is the hostname of server 1. Now when log emails are generated by cpanel from;

    - root@cp.server1.com (my office email set in .forward file under ~ for root)
    - cpanel@cp.server1.com (my office email set in .forward file under ~ for cpanel)
    - nobody@cp.server1.com (my office email set in .forward file under ~ for nobody)

    I get the following in exim logs;

    2006-06-09 23:21:15 1Fou05-000KJx-M1 <= root@cp.server1.com U=root P=local S=611525
    2006-06-09 23:21:15 1Fou05-000KJx-M1 remote host address is the local host: cp.server1.com
    2006-06-09 23:21:15 1Fou05-000KJx-M1 == root@cp.server1.com R=lookuphost defer (-1): remote host address is the local host
    2006-06-09 23:21:15 1Fou05-000KJx-M1 Frozen

    The email! ... rather than getting forwarded to my office address, gets frozen in the server queue. At server 3 (where my office email is hosted), I get;

    2006-06-01 09:59:22 H=(cp.server1.com) [xx.xx.xx.xx(IP of server1)] sender verify fail for <root@cp.server1.com>: response to "RCPT TO:<root@cp.server1.c
    om>" from mail.server1.com [xx.xxx.xxx.xxx(IP of server2)] was: 550-cp.server3.com [xx.xxx.xxx.xxx (ip of server 3)] is currently not permitted to relay\n550-th
    rough this server. Perhaps you have not logged into the pop/imap server\n550-in the last 30 minutes or do not have SMTP Authenticati
    on turned on in your\n550 email client.
    2006-06-01 09:59:22 H=(cp.server1.com) [xx.xx.xx.xx(ip of server 1)] F=<root@cp.server1.com> rejected RCPT <my-office-email-address@office-domain.com>: Sender verify fail
    ed

    Note: At some later time, domain server1.com is to be shifted from server 2 to server 1. Prior to this, the domain server1.com was shifted from server1 to server 2, so that server 1 could be re-built. After re-building server 1, it is back up now. But! untill the websites/domain.tld is shifted, I need to get logs from server1 to reach my office email.
