    Hello,

    I'm trying to send mail from mysite.com (my own server), to a remote server that hosts user@remotesite.org (the user does exist!)

    From server1.myhost.com as root I ran:

    Code:
    exim -bt user@remotesite.org
    user@remotesite.org is undeliverable: No Such User Here
    From server2.myhost.com (that is located at the same rack as server1):

    Code:
    exim -bt user@remotesite.org
    user@remotesite.org
      router = lookuphost, transport = remote_smtp
      host lobosuelto.arnet.com.ar   [200.45.191.210] MX=5
      host corderoatado.arnet.com.ar [200.45.191.211] MX=5
    From server3.myhost.com (another server on another different rack):

    Code:
    exim -bt user@remotesite.org
    user@remotesite.org
      router = lookuphost, transport = remote_smtp
      host lobosuelto.arnet.com.ar   [200.45.191.210] MX=5
      host corderoatado.arnet.com.ar [200.45.191.211] MX=5
    On the three servers I'm using the exact same Exim configuration, the same name servers at /etc/resolv.conf, same cPanel Release version, but I still don't understand why at server1.myhost.comI got the error. The only difference is that at server1.myhost.comI'm running CentOS 5, instead of RHE 5.2 (server #2 and #3).

    Already tried disabling Sender Verification/Callouts at Exim Config, resetting exim config to default but the error stills.

    Any suggestions about this?

    Thanks

    Is there any chance that remotesite.org is configured on server #1 as a local domain? It sounds as of Server 1 may think that remotesite.org is actually a local site, already configured, but without the user user@remotesite.org in it.

    Check your /etc/localdomains for any reference to remotesite.org

    That was the problem, time ago my customer had this site hosted on his Reseller account and the owner of remotesite.org moved to another hosting provider, my customer never deleted remotesite.org from his Reseller account, that was the problem!

    Thank you very much Mike! :)
