Mail-Via= DISTRIBUTE | DIST2 | Direct

This keyword is not available in LISTSERV Lite.

The default value is Mail-Via= DISTRIBUTE. DIST2 is functionally equivalent to DISTRIBUTE, and is included for historical reasons.

The Mail-Via keyword should generally NEVER be set, except by the LISTSERV maintainer for troubleshooting mail delivery problems.

On "Networked" and "Tableless" LISTSERV sites, Mail-Via= DISTRIBUTE causes mail to go out over the DISTRIBUTE backbone to spread the delivery load over the LISTSERV Network. Mail-Via= Direct causes LISTSERV to send all mail through the local SMTP server.

On "Standalone" LISTSERV sites, it has no practical use.
