That's system-dependent. You can be case sensitive or not as you see fit. However, many systems out there are not case-preserving; you'll find that addresses are sometimes converted to all-lowercase or all-uppercase. So the norm nowadays is to be case-insensitive. And as Chris correctly points out, it's mandatory to accept 'PoStmAster' in any combination of upper/lower case. -- dwmw2 -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
