Yet another random wifi network to connect to - this time in a small cottage in Slovenia. It actually allows access to internet, allows me to setup a VPN, so all seems well. Except for one little thingie: for some reason, it blocks outgoing SMTP traffic.
Well, no problem, there. I want to mail from my laptop, and it delivers to the mail server on my server. No problem there, if I route the traffic through the VPN, right? Wrong. After setting up the VPN it is still not working.
