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

SYMPTOMS

Under certain circumstances, the Microsoft Exchange Message Transfer Agent (MTA) will log an error similar to the following 251 error in the Windows NT Event Log:

CAUSE

This error will occur if the MTA is not restarted after the administrator adds an additional 30 MTA's to the same site.

WORKAROUND

Restart the MTA that is generating the Windows NT Event Log error. This will reload the MTA's memory listing of the site's configuration.
