Microsoft Plus! Internet Mail Client Service Uses POP3 Port ID

• Microsoft Windows 95
• Microsoft Plus! for Windows 95

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.

SYMPTOMS

You may experience problems sending and receiving e-mail using the Internet mail service in Microsoft Plus! for Windows 95.

CAUSE

The Internet mail service listens on the standard 110 port ID for POP3 mail, as specified in the RFC 1060 specification. If your POP3 mail server does not use port ID 110, you cannot send or receive mail.

RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

If your POP3 mail server does not use port ID 110, you can edit the value name

   00036651

   HKEY_CURRENT_USER\Software\Microsoft\Windows Messaging Subsystem\
   Profiles\<profile name>\<key>

The default value for port ID 110 (in hexadecimal format) is:

   6E 00 00 00

To enter the value 1F AE 00 00 in reverse notation, enter the value:

   AE 1F 00 00

MORE INFORMATION

Although you can specify a different port ID in a Services.ini file, the Microsoft Exchange Internet mail client does not look there for it. The port ID is listed in the registry and can be changed only by editing the registry.
