okay, i take it back.

WordPress is not encoding it in base64, it’s simply leaving it in base64, because the blackberry sends e-mails in base64.

either way, here’s what i did to fix it:
in wp-mail.php, under the lines:

if (stripos($content_transfer_encoding, "quoted-printable") !== false) {
		$content = quoted_printable_decode($content);
	}

i put:

if (strcmp($content_transfer_encoding, 'base64')==0){
		$content = base64_decode($content);
	}

i’m not a php wizard, but basically what it says, if the encoding is base64, decode the content.

i have the same problem too.

short answer: WordPress is encoding it in base64 for some reason. Using a base64 decoder (https://www.opinionatedgeek.com/dotnet/tools/Base64Decode/Default.aspx) with your pasted text gave me your post back in plain text.

i do not know how to fix this.
