F=3

Extend quoted-printable to EBCDIC V8.7 and above

When sendmail is required to convert a message body into quoted-printable form as determined by the EightBitMode option (EightBitMode), it ordinarily converts only those characters that are required by RFC1521. Unfortunately, mail that is transmitted to some IBM machines ( specifically those that speak EBCDIC instead of ASCII) can become garbled because of the way EBCDIC represents (or fails to represent) certain characters. Those characters are:

 ! " # $ @ \ [  ] ^ ` {  } ~ 

When sending MIME mail to such sites, you should probably set the F=3 delivery agent flag for any delivery agents that handle those sites. Setting this delivery agent flag tells sendmail to encode those characters, in addition to those normally encoded, using quoted-printable .

Note that sendmail does this encoding only if 8-bit characters appear in the message. This delivery agent flag solves one EBCDIC problem but should not be thought of as a general solution for all EBCDIC problems.
