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.
