Why does my email from Facebook have cut off lines?

Hello,

Are you having a problem seeing all of the lines in some of your email from Facebook?

According to Markus Stumpf on the qmail mailing list:

Facebook is sending their mails as
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="UTF-8"

Despite the fact that RFC2045 clearly states:

(Soft Line Breaks) The Quoted-Printable encoding REQUIRES that
encoded lines be no more than 76 characters long. If longer
lines are to be encoded with the Quoted-Printable encoding,
"soft" line breaks must be used. An equal sign as the last
character on a encoded line indicates such a non-significant
("soft") line break in the encoded text.

They are sending lines with some 100 chars wide.

This leads to some (correct) mail clients truncating lines and displaying garbled messages/text.

Also - as spammers make the same mistake rather often - I've seen line
length checks for Quoted-Printable implemented in antispam software.

I have notified Facebook, but don't expect something to happen. This was the answer:

facebook said:
I apologize for this inconvenience. Unfortunately, this is not an error on our end. You will need to speak with your email provider in order the resolve this issue.
