Can Send But Not Receive After Modifying Postfix master.cf file

Up until now, I have been using ports 110 for POP and port 25 for smtp on my Outlook client without issues. Last night, Comcast started blocking PORT 25 on my home internet connection, so I needed to begin using a new port for outbound (SMTP). Some info I sound on the Virtualmin support site seemed pretty straight forward explaining how to change the email account settings in Outlook to use PORT 587. I set it in SMTP and did not use any encryption (none). I'm not interested in using encryption at this time.

Changing just this on my email client did not work.

So I researched a bit in Virtualmin Support and found posts that said to un-comment specific lines in the master.cf file.

Well I did, and I was then able to send normally again......but now I cannot receive.

I've restarted postfix to check the logs but can't see where the problem is. I am pasting the contents of the master.cf file below as it is right now. Does this look right? Please help ;/
