Hello guys,

It seems that the smtp server that the list is using, does not behave
like the recommended smtp standards for sending email. I love to get
mail from the  openchrome mailing list, but with the current smtp sender
it will get blocked.

Is it possible to use a more secure smtp service? so that we increase
the security of the internet and live more closely to the open standards?

Thank you all,

Kind regards,

Jelle
