      [root@xenserver2 ssmtp]# sudo mdadm --monitor --scan --test -1
      sendmail: Cannot open mail:25

      Any ideas?

      Can you post the output of this

       cat /etc/ssmtp.conf

        BTW this is not using gmail, using our Cox smarthost with no auth/security

        Have you tested to see if your ISP allows port 25 out? Not all do. Also, is Sendmail or Postfix listening locally? Let's start there as that is easy:

        netstat -tulpn | grep 25

        What is the output?

          Just use gmail, accounts are free, and super simple to setup.

                You have no email server. That will do it.

                yum -y install postfix

                    Unfortunately, I have no clue what this means.

                      Ah, the ever present "no repos" in XS. Nice to see you again.

                      Boy does XS like being an appliance, or what?

                        Do this...

                        yum-config-manager --enable base
yum-config-manager --enable extras
yum-config-manager --enable updates
yum-config-manager --enable centosplus

                        Then install again.

                          Does the ssmtp at the end of the prompt make a difference? Shouldn't it just be [root@xenserver2] ?

                            That ssmtp at the end of the prompt is just showing you your folder location, no big deal.

                              Does Xen not have yum-config-manager installed these days? What a pain.

                              Anyone have the commands handy for enabling the repos manually?

                                        You just keep thinking that.

                                        I seem to remember the final words before giving up were
                                        "Why do you need this app installed anyway"
                                        And we found another option.

                                        But I could be wrong. 🙂

                                          Just a guess..

                                          For 6.5

                                          sudo yum --enablerepo=base --disablerepo=citrix install postfix
