Hi V11 :
1- from the link I mentioned , you should have read :
Extract the 2 files (libeay32.dll and ssleay32.dll) into the POP Peeper installation folder (typically, c:\Program Files\POP Peeper)
In POP Peeper, go to the "About" page, and click on the "Plugins" button -- make sure that "SSL" is checked.
For each POP3 account that you want to enable SSL:
Edit the account (select the account, press the "edit" button)
Check "Use SSL" (to the right of "Server Type")
Ensure the "port" is correct (for SSL connections, this is typically 995)
2- so there is no .exe , in fact .
3- for Gmail please follow the instructions in [How do I setup POP Peeper to work with my GMail account?] at http://www.poppeeper.com/faq.php?q=GMailPop3
4- about Removal please check Help> Remove Messages not on Server .
5- also , if you download the msg using your Email Client , it (the Client)will or not remove the msg from the server , depending on the account definition you made (in the Email Client) .
6- Next time PP checks that account , if the msg is not on the server anylonger , then PP will Remove the Message (from PP files) according to your option for that account .
