In providing support, I have discovered three lines of code that appeared in v1.1.0 and exist in the latest release.
The three lines of code affect Sendmail functionality. The next release (which I will get out by end of today) have:
- fixed an issue with the Sendmail functionality where some errant code is breaking message output three lines of code had to be removed - those are:
if ($to!='') {
fwrite($bk[0], "To: " . $to . self::CRLF);
}
- in version 1.1.0 those appear at lines 1770 to 1772
- in version 2024.1.2.1 those appear at lines 1516 to 1518
(remove all three lines) to fix issue - fixed in v2024.1.0
Did not help
Rather than rush the release of v1.3.0, I have posted an interim update that fixes the above problem. It's at https://sourceforge.net/projects/phpmailerpro/files/
