Odd hostname (and resulting e-mail) problem.

    I've had this problem happen a couple of times recently, the second time last night (early hours of the 5th), which makes me think it's happening because of the upgrade script.

    WHM version: 11.26.20

    Basically, the hostname gets truncated from uk2.exampledomain.com to just "uk2" - this then means that e-mail fails as it tries to deliver to "username@uk2". To fix it I have to reset the hostname and then run "/scripts/eximup --force" so that e-mail will be delivered (locally) again.

    Has anyone else experienced this and/or know anything about it?

    Is the server a VPS, such as OpenVZ or Virtuozzo? What is the output from the following command:
    Code:
    uname -srvmpio && grep -H '' /etc/redhat-release /var/cpanel/envtype
    If the environment type is OpenVZ/Virtuozzo, do you have root access to the hardware node configuration of the virtual environment that controls the VPS container? I ask because I have seen this problem on older versions of OpenVZ/Virtuozzo. If this is the same issue I am thinking of, it can be easily resolved by updating to the latest version of OpenVZ/Virtuozzo from the hardware node. Here is a related bug report from the OpenVZ Bugzilla web site, OpenVZ Bug 1087 – hostname - FQDN or not, with special attention to Comment #8 that is applicable to RHEL and CentOS Linux systems.

    Apologies for the delay in replying - I did forget to say that it is a VPS and that it is running on OpenVZ. I don't have access to see what version it is.

    As a side note, I have updated WHM/cPanel to 11.28.75 and it still happens.

    I shall point the ISP to this thread.
