That seems to be the consensus. I ran across a StackExchange discussion 
about being unable to trigger procmail.

Possibly. I will take a look at fetchmail. Thank you.  The advantage I 
have with gmail is that I can access it through the web. I really don't

I'd run across notmuch and was very confused since it kept saying it 
didn't do much but people were singing its praise.  I will see if I can 
find some more info on it.
