Microsoft Exchange 2003 POP3 server version 6.0.4417.0 (your_server_name) ready.
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, Change the SMTP Banner or Change the Telnet 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:
