#40 opendkim/README: HANDLING 8-BIT MESSAGES

[Dilian Wesselinov Palauzov]

The advice for define(confSEVEN_BIT_INPUT',true) shall mention that sendmail rewrites in 8bit messages the byte sequence C2 A0 (NO-BREAK SPACE) to the bytes 42 20 , which is B and space, In turn users complain that the mail they sent is visually modified during transport.

The opendkim/README shall state also the disadvantages of confSEVEN_BIT_INPUT, so that opendkim's user can weight the arguments. In particulat that without that SEVEN_BIT_INPUT rewritings there is no downside, if all MTAs on the way know 8BIT SMTP. But with confSEVEN_BIT_INPUT=true the 8bit emails are always misformed.
