I just installed the xampp version 1.8.3 and wanted to send a test mail (sendmail function) over a php script (PHP-Mailer class). This was formerly also no problem.
I configured the php.ini and sendmail.ini to set up my mail server data (tested with a gmx and a strato mail address) the same way i did it in the past.
But when i try to send a mail, i get a error message "Message could not be sent". The error log file told me, that the server replies that i am not using a ssl connection.
But i used the smtp port 465 or 587 in the php.ini and sendmail.ini (according to the FAQ of the provider).
Question: Do i need to install a special ssl certificate or something like this? I thought that i only have to tell sendmail to use ssl (or tls).
