This is not a "quopri" problem but an SMTP problem.

The SMTP protocol requires that a dot at the beginning of a line
is escaped by doubling (because it uses a line consisting of a
single dot as end of message indicator). Of course, the SMTP reader
is expected to remove this dublicated dot again.
Somehow, your SMTL sender or reader got something wrong with
the handling of a dots at the beginning of a line.
