Oh, you would absolutely shudder if you knew the state of the majority
of ISPs in Japan.

Your question, however, lead me to the answer to how to get postfix to
accept the mail.
By adding `` smtpname "name@my.domain" `` to .fetchmailrc, the problem
was solved.

The following postfix configuration apparently was okay.

Many thanks also go to Rhialto and Bruce for turning me on to the "mda"
keyword.  That hint helped me understand why sendmail (an mta) had
been working for me, while I had initial problems with postfix.  While I do use
procmail, it would require more caution in taking mail from fetchmail than I
feel confident with.  I'll be looking into maildrop; sounds like a
nifty program.
