    We have an account how is having a problem sending/recieving email from their rice.edu email account from our server and haven't been able to quiet figure out if it's on our end or the remote server.

    From the command line to test the account this:
    Code:
    exim -bt xxxxx@rice.edu
    xxxxx@rice.edu cannot be resolved at this time:
    host lookup did not complete
    
    From the exim_mainlog I found this:

    Code:
    /var/log/exim_mainlog
    2004-08-19 17:21:12 H=imf25aec.mail.bellsouth.net [205.152.59.73] sender verify defer for <xxxx@rice.edu>: host
     lookup did not complete

    Is this a problem on our server or with the rice.edu mail server ??

    Any help much appreciated :)

    Go on, have a guess
    Does a normal resolve work on your server:

    dig rice.edu

    and

    dig MX rice.edu

    Problem Resolved.

    yes, both results are working now!

    After some further investigations, I found that the IP used by rice.edu was being blocked for some reason in the deny_hosts.rules used by APF firewall... after removing it, all worked fine again. Not sure how their CIDR IP group got in there tho :)

    thx's for the help.
