[SM-USERS] force TLS1.1 or later

[David C. <da...@di...>]

Hello

 

I'm using Squirrelmail 1.4.22-16 on an Oracle Linux 6 with PHP 5.3.3

It's running on old hardware so probably it won't be upgraded anytime soon. 

Squirrelmail is working fine for many years, but I wanted to disable TLS1
support in sendmail. As soon as I do it, I get "Can't open Stream" error
message. Changed port 465 to 587 but I get the same error.

This PHP version supports TLS1.1 and 1.2, so,  is there a way to "force"
squirrelmail to use these later protocols? 

 

Kind regards

David
