We are running RH V7.2 on a Linux s390 VM. There is a great mirror site at ftp://mirror.mcs.anl.gov/pub/redhat/redhat/linux/7.2/en/os/s390/RedHat/RPMS/, that seems to omit some RPMs such as the one for the Postfix MTA. One thing I have noticed is that when I have to go outside this safe haven, the unlisted RPM's fail installation most of the time due to incompatibilities with the recommended GLIBC. This is the case with Postfix. The standard GLIBC RPM's for this distribution are at v2.2.4-24, and the Postfix RPM (among others) requires an older version of GLIBC (IE v2.3.1 or thereabouts).
I am inclined to suspect that I need to back rev the GLIBC. But I am loath to confront what I feel would be a lot of dependency problems. Alternatively, since I am mainly interested in evaluating Email Server solutions (IE freebies or demo versions will take priority over 5-user licensed versions), perhaps I should ask what Email Server solutions I should be looking at with this distribution. Thank you in advance for your time.
