To all who have helped me so far, a huge thank you! I soon realized that the subject line of this message is incorrect since pop3 covers only the delivery task and I got that working a couple of weeks or so ago. The indescribably joyful experience of being able to successfully authenticate to an out-going smtp smarthost that my ISP provides, however, has more than made up for the false sense of "mission accomplished" I felt when the first pop3 message popped up.
I did take the output of an unsuccessful authentication attempt and ran the base64 string it returned as the password through base64 in decode mode and, voila, there was my user ID and password in nice clear text as it should be and there's where I found the last unexplainable reason for failure. In .msmtprc, there is a line that looks like: password 'BiG-SeCreT' I wanted to be really concise so I enclosed the secret in single quotes just as you see it here. I expected msmtp to strip those out and that would insure that what was there was always taken literally. What's there is taken literally, all right including the single quotes. I took them out and I can now see that authentication is successful and a couple of test messages went out and have arrived at a remote host in 1 piece so I technically can send mail but I still need to tie msmtp in to nmh which some of you may be familiar with. That is a different topic for a different mailing list. Again, thanks to all for your patience.
