We need to get openemm installed on a CentOS 6 x64 server. Sendmail is the MTA of choice. And openemm needs to be installed from source package rather than an rpm.
*Please note that you need to have prior experience of installing openemm on this configuration. Even if you've worked with earlier on a different distribution or CentOS5, I would suggest that you may try installing it on a virtual machine and see if it works first.*
