New Setup of Asa 5505 problem of outlook logging into server to download email

I have recently setup asa 5505 to allow for inbound smtp to from outside connections. Email is getting to server just fine. I can forward email from mailbox to alternate email address example a yahoo account. But the problem I have is that outlook is having problems logging into pop3 account to receive email. I have the esmtp filter off and have the below configs

You need a NAT entry for pop3

If you're just using a client PC with Outlook that is on your inside interface and using Outlook to check a POP3 e-mail account that is on an external host on the Internet, you do not need an explicit NAT for POP3.  You're existing configuration looks OK and you should be able to retrieve POP3 e-mail just fine.

What error or behavior are you seeing in Outlook when you try to download POP3 e-mail?

You need a static route for pop3.
