I would not qualify this as malformed - it is valid RFC2047 Q-encoding , which is folded (see RFC 822 section 3.1.1) to avoid header corruption when the lines are longer than 63 chars. If your software is choking on that, then it means it is not standards-compliant. The change in behavior was introduced in PHPMailer 6.1 (see https://github.com/PHPMailer/PHPMailer/pull/1840), MantisBT release 2.23.0. |

Okay, I learned something today ! I'm not really surprised that Outlook isn't standards-compliant, but more about Zimbra and Thunderbird. |
|
TBH, I'm not an expert, but PHPMailer's maintainer is so I'm pretty sure he fully validated that before merging the change. BTW You have not explained what the actual problem is, on the mail client side. |

Forgive me for not being explicit in the ticket. |
