TLS Smtp check


Encontré un sitio donde verificar si tu servidor de correo acepta trabajar con TLS, lo que haría un poco mas seguro la recepción de emails, siempre y cuando el originante del correo también lo pueda activar y sesionen.

http://checktls.com/perl/TestReceiver.pl



Checking dac@dcialdella.no-ip.com

looking up MX hosts on domain "dcialdella.no-ip.com"

No Mail eXchangers found; will try TLS directly to host

Trying TLS on dcialdella.no-ip.com[85.251.210.44] (0):
