I envoke fetchmail with a simple command line fetchmail, no options except those
in my .fetchmailrc file. Here is my .fetchmailrc file:

# Configuration created Sun Jul 11 10:36:42 2004 by fetchmailconf
set postmaster "rmiles"
set bouncemail
set no spambounce
set properties ""
set daemon 90
poll mail.comcast.net with proto POP3
       user 'r.godzilla' there with password '*******' is 'rmiles' here

I have put asterisks where the password goes. I run singledrop. I do not start
it in a cronjob. It runs in daemon mode.
I will take your suggestion and use -v -v command line options to capture the
control messages between the server. The mail server does not keep messages.
Should I use the -K option to ensure the fetched mail is removed from the
server?

I will let you know how the log of communications turns out.
Thank you for your assistance.
