I have the same problem without ubufox...
I've tried to make a traceroute to webmail-estudiante.uam.es and this is what I get:
pablo@pandora:~$ traceroute webmail-estudiante.uam.es traceroute to webmail-estudiante.uam.es (150.244.9.34), 30 hops max, 40 byte packets 1 pandora.local (192.168.1.34) 0.380 ms 0.699 ms 0.908 ms
And a ping to the ip of webmail-estudiante.uam.es, 150.244.9.34, says "Destination Port Unreachable".
I don't know where can be the problem.
