The information in this article applies to:
  • Microsoft Exchange Server, version 4.0

SUMMARY

When you use the Microsoft Exchange Internet Mail Connector (IMC) and you have two routes (address spaces), one with SMTP: and one with SMTP:*, mail will move on the SMTP:* route even if the cost for this route is higher than the SMTP: route.

Routing returns four values in order of "best fit" as follows:

  • Exact match
  • Wildcard match
  • Partial substring match
  • No match

SMTP:* is considered a wildcard match and SMTP: is considered a partial substring match.
