 +^ This page only applies to the old POPFile 1.1.1 release and the earlier releases which offer support for SSL connections to mail servers ^
  
 +^ POPFile 1.1.2 (or later) uses improved SSL support which is built-in to the installer and does not involve any internet access during installation ^
 +
 +For POPFile 1.1.2 (released 21 August 2011) the SSL support for the Windows version was upgraded to use a completely new SSL support package which is more up-to-date and smaller than the support packages used by earlier releases of POPFile. The Windows installer now includes all of the neceassry files and installs them by default. This means the installer will no longer download (and possibly patch) the files during the installation. As a result the installer code has been simplified and made easier to maintain.

 POPFile has been able to make SSL connections to mail servers since the 0.22.0 release in September 2004. If the "SSL support" option is selected the installer will download the necessary files from the University of Winnipeg repository (this is the main source of these SSL Support files; they are not available from the main %%ActivePerl%% 5.8 repository because %%ActiveState%% do not currently have the necessary government permit). POPFile has been able to make SSL connections to mail servers since the 0.22.0 release in September 2004.

 +POPFile 1.1.0 and later releases also download one SSL file from the ppm.tcool.org repository because the file found in the University of Winnipeg repository does not support the timeout feature POPFile uses to cope with slow servers.
  
 Downloading the SSL support files during the installation helps reduce the size of the installer and ensures that the installation uses the most up-to-date SSL support files. This scheme has worked very well because these SSL files are not updated frequently (see [[#SSL Support Files Status|table]] below). Downloading the SSL support files during the installation helps reduce the size of the installer and ensures that the installation uses the most up-to-date SSL support files.

-  * On 22 June 2005 the University of Winnipeg's SSL files were updated to work with ActivePerl 5.8.7 Build 813 (the then current version of ActivePerl). These changes made the SSL files incompatible with the Windows versions of POPFile 0.22.0, 0.22.1 and 0.22.2 since these releases use older versions of perl58.dll which lack some of the features required by the new SSL Support files. This binary incompatibility prompted the release of POPFile 0.22.3.+  * On 22 June 2005 the University of Winnipeg's SSL files were updated to work with %%ActivePerl%% 5.8.7 Build 813 (the then current version of %%ActivePerl%%).
