How can I
change the POP3 banner seen when
connecting to my Exchange server?
MS KB article
303513 has more:
When you connect to an
Exchange 2000/2003 server with the Post
Office Protocol (POP) you receive a
banner that is similar to the following:
Note: The POP3
banner has another function. Read Remote
Version Checking through
SMTP/POP3/IMAP4.
Note: You may also
want to Change the IMAP4 Banner or
Change the SMTP Banner.
WARNING: If you
use the ADSI Edit snap-in, the LDP
utility, or any other LDAP version 3
client, and you incorrectly modify the
attributes of Active Directory objects,
you can cause serious problems. These
problems may require you to reinstall
Microsoft Windows 2000/2003 Server,
Microsoft Exchange 2000/2003 Server, or
both. Microsoft cannot guarantee that
problems that occur if you incorrectly
modify Active Directory object
attributes can be solved. Modify these
attributes at your own risk.
This may be an issue if
you do not want the version of the SMTP
service that is running on your server
to be displayed. To remove the version
information from the Windows 2000 SMTP
banner, follow these steps:
Note: The
following screenshots were taken on a
Windows Server 2003 computer running
Exchange 2003. I bet you can find your
way on a similar W2K + E2K computer.
-
Using a metabase
editing tool such as MetaEdit or
Metabase Explorer,
locate the following file:
Lm\POP3SVC\virtual server number
-
Click Edit, click
New, and then click String Record.
-
Verify that the entry
in the ID box is Other, and then
type 41661 (decimal) on the right
side of the ID box.
-
In the Data box, type
the banner that you want to be
displayed. Or, if you're using
Windows Server 2003 and the IIS 6.0
version of Metaedit, double click
the new value you've added and enter
the text you want to be displayed.
-
Stop, and then
restart the POP3 virtual server or
the POP3 service.
-
To confirm that the
banner has been changed, telnet to
port 110 of the virtual server (the
default setting). The original
banner should no longer be
displayed.
