- Welcome to the reality of modern mailers! Blank stripping is extremely
- common, widespread, and actually unavoidable in many contexts. In particular,
- mailers that have been extended to deal with BITNET messages have to learn to
- both strip extraneous blanks that are added as well as to expect trailing
- blanks to disappear.
-
- This behavior is not legal within the strict confines of Internet messaging.
- However, most of the cases where stripping happens are outside the realm
- where Internet standards can be strictly applied.
-
- So, your answers are: (1) Your experiment isn't bogus, but it only served to
- illustrate common behavior, (2) MX probably does strip blanks since it has
- to deal with BITNET, (3) Stripping blanks is neither legal nor illegal, and
- (4) Blank stripping should not be done unless absolutely necessary, but it
- is often necessary.
-
- Blank stripping affects several encoding formats badly (some UUENCODEs
- in particular) so it is important that if you elect to encode messages to
- eliminate blanks stripping you do so in a way where the cure isn't worse
- than the disease. Both of the approved MIME encodings for messages were
- designed with full knowledge of this and are therefore immune to blank
- addition or stripping. Needless to say, they both protect their contents
- as any encoding should.
