The problem seems to be associated with Content-Transfer-Encoding. The one causing these problems seems to be
Content-Transfer-Encoding: quoted-printable.
Most email services are good at processing out the quoted-printable codes, but Microsoft-based emails are apparently maintaining a kind of legacy approach that does not correct for these. The internet is FULL of complaints about this issue. Even though PHPMailer is set to 8bit by default, it appears to be changed to quoted-printable by mail servers such as Microsoft. The result is that any line that of text that exceeds 76 characters gets something like
"=
=3D=0A="
inserted at the 76th character spot.
After days of testing and research, I have discovered that I can solve this issue if I change the following setting in CBPHPMailer.php from "8bit" to "base64":
Code:
/**
* The message encoding.
* Options: "8bit", "7bit", "binary", "base64", and "quoted-printable".
* @var string
*/
public $Encoding = 'base64';
Set to base64, properly formatted emails are delivered to hotmail and outlook email users.
Does that make sense? And more importantly, will our modified message encoding setting be removed anytime we update Community Builder? If so, is there some way that we can keep it in place?
