Is quoted-printable enough to make a mail compliant with the line-length-restriction posed in RFC 2822?
- by Mnementh
In RFC 2822 (defining E-Mail) is defined, that no line SHOULD be longer than 78 chars (excluding CRLF) and MUST not longer than 998 characters. With quoted-printable longer lines will be broken into more lines, ending each with a '=' until the real linebreak is reached. Conforms a mail to the standard, if it contains lines longer than 78 (or 998) characters but is encoded with quoted-printable?
There are arguments, that this isn't compliant, because the receiving mail-client has longer lines after decoding the quoted-printable message.
