Displays SMTP routing information. If you omit destination, you see the entries in the local Mail Exchange (MX) database. If you specify destination, you see all the entries in all the databases that DIGITAL TCP/IP Services for OpenVMS would look at, if necessary, to resolve the address.To send mail, SMTP looks up addresses in one or more databases (if necessary) in the order listed below.
- Local MX databse
- Remote MX database
- BIND server database
- Local hosts database

Displays, in order of preference, the routing hops to reach host SWAN if an attempt fails. The local host tries to route through:
- WATER.PIPIT.WEBBED.FEET.COM
- bd-gw.purple.martin.com
- great.horned.owl.com
- bird.food.seeds.worms.com
Both the alternate gateway and the zone affect how SMTP decides where to relay non-local mail.
MX records tell mailers where to relay mail that is destined for a given host. In the display:
- The Gate name field tells where to relay the mail.
- The Gate address field gives the gateway's IP address.
- The Preference field gives each MX record a precedence. Lower preference number means higher precedence.

TCPIP> SHOW MX_RECORD CROW.COM
BIND MX database
Server: 18.18.218.10 WATER.PIPIT.WEBBED.FEET.COM
Gate address Preference Gate name
159.228.12.253 1 cawcaw.crow.com
159.228.12.254 2 scare.crow.com
TCPIP>
|
Displays the MX record for destination host crow.com. In the display:
- The Gate name field tells where to relay the mail.
- The Gate address field gives the gateway's IP address.
- The Preference field gives each MX record a precedence. A lower preference number means higher precedence.
In this example, the local host name is WATER, the alternate gateway is scare.crow.com, and the zone is crow.com. The first preference for delivering mail to crow.com is to try to send to cawcaw.crow.com.
If you have not defined an alternate gateway, SMTP tries to relay the mail to scare.crow at IP address 158.228.12.253. It uses the MX records to decide on the host to which to relay mail. SMTP tries to relay the mail to each gateway host, in order of preference, until it either successfully transfers the mail or runs out of MX records to try. If there is no alternate gateway, zone is not used.
If you have defined an alternate gateway, SMTP goes through the list of MX records, but it does not automatically try to relay the mail directly to the gateway. SMTP checks whether the gateway host name is outside or inside the SMTP zone (as defined with SET SMTP CONFIGURATION). If the gateway is inside the SMTP zone, SMTP tries to relay the mail directly to the gateway host. If the gateway is outside the zone, SMTP sends the mail to the alternate gateway.
