In the
Requestor E-mail Addresses box, type the e-mail addresses for all valid requestor agents. This prevents users from creating rogue requestor agents and participating in the InterOrg directory scheme. These addresses should be the Simple Mail Transfer Protocol (SMTP) addresses of the requestor services except if the master and requestor service are both installed on the same Exchange Server computer (as is the
case for the master Exchange Server computer).
