A filter that armors lines beginning with
"From "by encoding theFwith quoted-printable encoding.From-armoring serves a similar purpose as MboxFromFilter, but replaces lines beginning with
"From "using"=46rom "instead of the irreversible">From "form. This requires the content modified by this filter to use quoted-printable transfer encoding in order to work properly.This armoring technique preserves content so receiving clients can still verify PGP/MIME and S/MIME signatures.
