Overview

You enabled TLS encryption using the $incomming_smtp_starttls_extension_enable="true" setting in your lmcfg.txt file and want to know how to disable SSLv2 and SSLv3 in ListManager.

Solution

1. Open the tclhttpd.rc file located in the bin directory ...listmanager\tclweb\bin with a plain text editor (such as Notepad or Wordpad) and edit the following line to be as follows:
   

   Config USE_SSL2 0
   Config USE_SSL3 0
   Config USE_TLS1 1

   NOTE: USE_SSL2 and USE_SSL3 should be set to 0 as these protocols are no longer secure.
   
   
2. Save the file and restart your ListManager server for the changes to take effect

After restarting ListManager SSLv2 and SSLv3 are disabled.
