Does LISTSERV support the following feature: When an identical message is sent to multiple mailing lists, subscribers who belong to more than one of those lists receive only one copy of the message? I understand that differences in message formating (e.g. headers, footers) between lists may make implementing such a scheme problematic, but apparently Majordomo can be configured to do this.
