ezmlm-idx>=0.23 allows alternate names for all user commands. This can be used to e.g. make a message to ‘list-remove@host’ to result in an ‘unsubscribe’ action. This may help migration from other mailing list managers and in non-English environments. The use of aliases allows ezmlm to respond to new command names, while always responding correctly to the standard commands. If ezmlm-request(1) is used it will automatically be able to deal with any commands you set up for the list, within ezmlm or as separate programs. See Multiple language support on how to set up command aliases.
