FIXLDAP
This program is only for VPOP3 version 2.0 or earlier.
FIXLDAP is a small utility that will check and fix the LDAPEXT.DBF used in current versions of VPOP3 for holding address book information. In some circumstances the file can get corrupted, and some bugs in certain versions of VPOP3 mean that some entries may not be visible to email clients. This utility will fix the most common problems.
To use FIXLDAP, stop VPOP3 running, then run FIXLDAP from a Command prompt in the VPOP3 directory. It should tell you what it's doing. Then restart VPOP3 once that has finished.
