Comment:

 Have to add to this conversation, that after 7 years, this issue was
 resolved by the current implementation of PHPMailer 5.5 made in 2020

 But now we are in 2025, and PHPMailer has kept evolving

 For example, no too far in the same year (2020), they released the version
 [https://github.com/PHPMailer/PHPMailer/blob/master/changelog.md#version-615
 -march-14th-2020 6.1.5] that ensures CRLF is used explicitly when needed,
 rather than `static::$LE`.

 Also, the 6.9.0 added the support for newer versions of PHP like 8.3. The
 thing is that I can't see any current maintainer of the Mail component.

 I'm removing the `needs-testing` tag because it doesn't apply anymore.

 I might look for further instructions in case anyone could be interesting
 in doing another version upgrade for the greater good.
