Hello,
this bug is still not fixed!
The lines 477 and 478 are:
$rgx = ($this->apply_windows_bugfix) ? Subject : Subject|To; // dont strip out To header for bugfix
if (!preg_match(/^.$rgx.$/i, $head)) $this->headers .= $head.: .strtr($value, "\r\n", )."\n";
And they have to be changed to:
$rgx = ($this->apply_windows_bugfix) ? ^Subject$ : ^Subject$|^To$; // dont strip out To header for bugfix
if (!preg_match(/.$rgx./i, $head)) $this->headers .= $head.: .strtr($value, "\r\n", )."\n";
Thanks,
Florian
