Looks like the PHP documentation has been updated to make more clear that the same 'line-length' parameter used by the base64 filter can also be used by the quoted-printable filter. So use that.

Looks like PHP's en-/decoding is indeed causing some problems. See the attached message.

I guess we have to live with it then. It doesn't make much sense to post-process the data. The benefit of using a php-internal implementation outweighs the readability loss IMO.

Not sure what we can do about this. Quoted-printable encoding is now done via a PHP stream filter, and this (encoding newlines) appears to be the expected behavior. See the example at: http://www.php.net/manual/en/filters.convert.php

Yes, this is the patch to make the test work again: http://cvs.horde.org/diff.php/framework/Mime/test/Horde/Mime/mail_003.phpt?r1=8d38a43880bfd2f005b63d098c51bb904cdaacfd&r2=3bf3c137d359062d2d9e04dfb60b10dbddf12e8e

Is this text/plain flowed data?

I'm not sure, but I think we are incorrectly encoding newlines when converting to quoted printable now. The longer stay as-is, but are converted to =0A. I don't see any other client doing this, and it makes the message source less readable, what the purpose of quoted printable vs. base64 is.
