6.2.19 Gate

Syntax:

Gate what

Examples:
Gate Zones
Gate Domains
Gate Both
Gate Ask

The what parameter to the Gate keyword specifies if MsgEd TE should do zone gating (Gate Zones), domain gating (Gate Domains), or both (Gate Both). If you specify Ask as parameter (this is also the default), you will be asked if you want to use zone gating for each inter-zone mail that you write.

This has nothing to do with internet gateways!

Domain gating is explained in detail in the section about the Domain keyword (see The Domain Keyword).

Zone gating works like this: If you write a mail to a node in a zone different from your own, and zone gating is enabled, the mail will not be addressed to the receiver in the other zone, but it will be addressed to that zone’s zone gate (which also has an address inside your own zone). The address of the true receiver will be encoded in an @INTL kludge line.

If you don’t have a direct inter-zone link set up in your tosser, you may always enable zone-gating on with the Zone parameter. All mail that crosses zone boundaries will then be sent via the zone gate, which is by far the most reliable mail to send inter-zone mail. If, on the other hand, you do have a direct inter-zone netmail link, you need the Ask parameter, because then you must decide for each netmail individually if it shall be sent directly via this link, or (probably because it is for a zone not covered by this link, or because the link partner has not agreed to forward mail not destined for himself) must be sent via the zone gate.

Turning zonegating off with the None parameter is not at all recommended. If you send inter-zone mail wihtout zone-gating, there only need be one single tosser on the routing path which does not recognise INTL kludges, and the mail will probably disappear. So, don’t turn off zonegating unless you have direct links for the destination zones you are writing mail to.
