Unless you're using recent mode to download mail to multiple clients, make sure you've opted not to leave messages on the server. Your POP settings in Gmail settings are what determines whether or not messages stay on the server, so this setting in your client won't affect how Gmail handles your mail.
If your client does not support SMTP authentication, you won't be able to send mail through your client using your Gmail address.
If you're having trouble sending mail but you've confirmed that encryption is active for SMTP in your mail client, try to configure your SMTP server on a different port (465 or 587).
