| 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 <tmp.tmp |
| |
| This just recreates the subscriber database with the old style hash. |
| |
| This procedure can also be used to recover corrupted subscriber databases, |
| by editing tmp.tmp before resubscribing. |
| |
| You can also identify the addresses that would be affected by: |
| |
| % ezmlm-list | grep -G '[A-Z]' |
| |
