<br>
It' of course possible to use TLS from within PHP. But what if that <br>
PHPMailer uses an ancient library that doesn't support the modern <br>
protocols and ciphers we're using?<br>
. <o:p></o:p></p>
<p class="MsoNormal">Thanks for that. I think you are spot on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For legacy reasons this particular site is still running on PHP 5 and looking on the web this would seem to be one of the reasons for PHPMailer using old protocols!<o:p></o:p></p>
<p class="MsoNormal">Also, I imagine the firmware on a lot of network scanners etc. also are badly out of date on TLS protocols which explains their problems.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Appreciate your input – at least I know have a clue as to what the problem may be.<o:p></o:p></p>
