Let me try to force a re-wrap to occur here: >23456789A123456789B123456789C123456789D123456789E123456789F123456789G12345= 6789H The specific nature of the problem seems to be that quoted-printable MIME parts seem to be getting unencoded and then re-encoded by the sourceware mail system. In doing so, the wrapping policy applied by the original mailer is destroyed, and sourceware's own is imposed. Clearly this is a bad thing, since unless the results of the policies are identical, the validity of any signature is destroyed. Is there a suitable sourceware administrator watching this thread, or should I summarize the issue to overseers@ ?
