I'm curious how a traveller is supposed to get SMTP relay service when, well, travelling. I am not really sure if I want a VPN for sending a simple email.
And I can understand (although I am not convinced that doing so is such a great idea) blocking 25/tcp outgoing, as most botnets will try that method of delivery. However, I do believe that outgoing 465 SHOULD always be allowed. regards Carlos On Tue, Oct 25, 2011 at 10:43 AM, Bjørn Mork <bj...@mork.no> wrote: > Owen DeLong <o...@delong.com> writes: > >> It's both unacceptable in my opinion and common.
