v2.2.0:: AutoMail Issue

Yes, it should.

Could you try to add a debug line :
[code type=php-brief]if (!$headers) {
$eol=(isset($paramMailEol))?$paramMailEol:"\r\n";
debugLog("NewLine=".strlen($eol).":".nin2hex($eol));
$headers = 'MIME-Version: 1.0' . $eol;
$headers .= 'Content-type: text/html; charset=utf-8' . $eol;
$headers .= 'From: ' . (($sender)?$sender:$paramMailSender) . $eol;
$headers .= 'Reply-To: ' . (($sender)?$sender:$paramMailReplyTo) . $eol;
$headers .= 'Content-Transfer-Encoding: 8bit' . $eol;
$headers .= 'X-Mailer: PHP/' . phpversion();
}[/code]

Then try again a copy here the log file.

Sorry there was a typo in the debug line :
I just found the issue, line 561 must be completed:You can remove the debug line !

Then it should work.
I include this fox in next version, so if you change it, you'll retrieve your parametering on next versions.

The fix appears in V2.5.0.

V2.4.3 was published on august 7th, 3 days before the identification of the fix.
