Hello Anthony! Thanks a lot for the valuable details! There will be very helpful for me. So, I can see now that I need to use SAN for our mail system. We use Debian, but rebuilding and pinning packages is not a big problem for me. I was doing similar things a few times before. Have a nice day, Pawel _______________________________________________ Obm mailing list [email protected] http://list.obm.org/mailman/listinfo/obm
