SUMMARY

This article outlines the different modes for the MailEnable VRFY command.

DETAIL

MailEnable's VRFY command has two modes of operation. These are outlined below.

The value is controlled by this key:

Root: HKEY_LOCAL_MACHINE\SOFTWARE\Mail Enable\Mail Enable\CONNECTORS\SMTP
Value Name: "Use Directory for VRFY"
Type: DWORD
Values: (follow)

0. Address Map resolution mode (default configuration)

In this case the VRFY query string is validated against all the addresses
served by MailEnable. (ie: the addresses in the address-map.tab file).

If a match is found then a 250 response is returned containing the original query string.

As such, whatever you ask for will be validated and will be returned in the string response.

In the case where the supplied e-mail address matches the query string, the VRFY query string will be returned in the following format:

250 <EMailAddress>


1. The VRFY query string is validated against the published contents of the MailEnable directory (Directory.tab file).

In this case where the directory provider is used (ie: this case) then the display name is used as the key for resolution. In the case where the display name matches the query string, the VRFY query string will be returned in the following format:

250 DisplayName <EMailAddress>
