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 ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
