DMS POP3 Server 1.5
A overflow problem has been identified in the POP3 Service version 1.5.3.27 and earlier.
When logging on to the POP3 server, if the username or password is longer than 1024 characters the POP3 service stops. The service can be restarted with the POP3 Server Settings or the Windows Services Control Panel Applet.
Version 1.5.4.27 of the pop3svr.exe fixes the problem. It
can be downloaded here.

You can check which version of the pop3srv.exe file you have from the Properties menu of the Windows Explorer. You can also check by logging on to the POP3 server with telnet.
C:\>telnet servername 110
+OK servername DMS POP3 Server 1.5.3.27 Ready
quit
+OK Goodbye
Connection to host lost.
C:\>
To replace the file follow these directions:
- First remove the service with the POP3 Server Settings program. From the General tab, right click the POP3 Service (Running) and select Remove from the popup menu. You can also select the POP3 Service in the Server Status display and click the Remove button.
- When the service has been removed, replace the pop3srv.exe file with the new one. If you accepted the defaults when you installed, the pop3srv.exe program will be in the C:\Program Files\DMS POP3 Server folder.
The self extracting zip file that you downloaded here
will place the new file in the default directory. If you
have installed to a different directory you will have to
manually unzip the file and copy it to the install
directory.
- Restart the POP3 Service from the POP3 Server Settings program. From the General tab, right click the POP3 Service (Not Installed) and select Install from the popup menu. You can also select the POP3 Service in the Server Status display and click the Install button.
To check that the new version is running:
C:\>telnet servername 110
+OK servername DMS POP3 Server 1.5.4.27 Ready
quit
+OK Goodbye
Connection to host lost.

If you have a lot of email traffic, you may want to shut down the SMTP server while you update the POP3 Service so that you don't loose any messages. You can stop the SMTP service from the Windows Services Control Panel Apple or from the POP3 Server Settings program. Restart the SMTP service after you have installed the new POP3 Service.
