Client Mail Server Again

     The client mail server locked up again as far as Network I/O goes.  I suspect this is a kernel problem but I don’t have any good options for this server as newer kernels don’t work correctly with the antique version of glibc on this machine and older kernels have a security exploit.

     I am continuing to work on a replacement server based upon Ubuntu so it will have current everything.  I’ve got most of the software installed, but still working on the configuration of dovecot and postfix which is not straight forward, especially in the case of postfix because it operates in a very different environment.  Under Ubuntu, it operates within a chroot jail, this provides additional security but requires changes to paths and other configuration items.  I hope to get it operational this weekend.
