Outbound SMTP (to relay)

relayhost = [eu-west-1.cp-mta.com]:587

This configuration forwards all outgoing mail to the smart host.

Note:

  • Use square brackets to reduce the risk of MX lookups (with brackets, no MX lookup will be done, only A/AAAA record lookup, direct delivery to this host is enforced).

  • Ensure that you enter the correct relay address. You can find the address in the Avanan Portal.
