Most newsreaders allow you to select which ports you want to use.  These port options may vary from newsreader to newsreader, but all Pure Usenet accounts come with ports 119, 80, 563 (SSL), and 443 (SSL) enabled.  In general, we suggest using ports 563 or 443, as both are SSL secured.

Note for users on slower/older computers:

When you have a older computer, download speed with SSL is slower because the processor cannot keep up with decrypting large files.  If you're experiencing speed issues and are using a secure port, changing to a non-SSL port (either 119 or 80) may speed up your downloads.
