popclient (and almost everything else) should invoke sendmail with the
`-i' or `-oi' option.  From the manpage smail(5):

       -i or -oi
              Do  not  allow a single `.' to end an incoming mes-
              sage.  Otherwise, a dot on a line  by  itself  will
              end  a  message.   This  is the default if smail is
              invoked as rmail.

This is less than helpful about what the default is when invoked as
/usr/sbin/sendmail, but - following sendmail's lead - the answer is
that a `.' on a line of its own ends the message.
