$Id: DOWNGRADE.idx 36 2003-12-18 19:26:32Z bruce $ MODIFYING ezmlm-idx lists to work with "virgin" ezmlm-0.53 With ezmlm-idx-0.22, the routines issub.c and subscribe.c are modified to store subscriber addresses using a hash based on the lower case address, rather than a case sensitive hash. This was done to avoid the many problems with subscribers using mixed case addresses (User@host and user@host) without realizing that these are different. These changes have no impact on lower case-only addresses. For mixed case addresses, the case in the local part is retained. If not found, a second lookup is done with a hash based on the mixed case address. This results in backwards compatibility with ezmlm-0.53 subscriber list. In the unlikely event that you use ezmlm-idx and then decide to go back to ezmlm-0.53 alone, mixed case addresses stored in the new location (case-insensitive hash) will not be found by the old ezmlm-0.53 programs. To place them in the ezmlm-0.53 position, do the following with your lists after installing the "virgin" ezmlm-0.53 binaries and backing up everything under DIR/subscribers: % ezmlm-list DIR >tmp.tmp % rm -rf DIR/subscribers/* % xargs ezmlm-sub DIR
