Hi gr5 ! Thanks for your answer.
I think that is our server which doesn't recognize the Ultimaker (and not an issue with the UM3), but as I'm not the person in charge of the network (Just a trainee needed by the company to try some new things with a 3D printer), I can't really try to do all things I want with the network.
I'll question my superior about taking it at home to find out if it's just the network that do not recognize it or something goes wrong with a capricious internet card.
Well, I'm not a pro with linux and SSH, but I will look at the possibility with connman. I didn't say that fixed IP is bad (I use it at home), but just that our DHCP should send any IP, and the printer is supposed to understand it, and the communication is supposed to be easy ?
I already questioned the man in charge if it possible with a MAC address, and his answer was negative, even if he didn't explain me why it's impossible..
If it's possible in connman, I'll probably try it ! But the issue which comes in mind : I'll have to be in my own wifi with the printer and the computer to use ssh. But if I try to log with the printer on the company network, it'll stop the ssh no ?
But before "playing" with the dev mode, I'll question the reseller to know if the printer stay under guarantee after use this mode.
Thanks for helping me ! (And sorry for the not perfect english)

It sounds like you are pretty good with computers. My printer works with DHCP fine. There's a small possibility that your printer has a defective ethernet connection. I would strongly consider taking it home or something and see if it works there.
Anyway if you can somehow get network access to it (for example using a crossover ethernet cable or by setting up a micro/private wifi access point only used by the um3 and one of your computers) then you can ssh into the printer (put it into developer mode first from the menu system) and you can setup the network anyway you want using conman. You can google about conman. I know you said "fixed ip is bad" but you should be able to tell the DHCP server to not send out a small range of ip addresses and you can assign one of those permanently to the UM3.
Other than that - it should just work. You can get the MAC address off the network screen on the UM3 (it's kind of hidden in the name but if you look for 12 hex digits you will find it) and then maybe the dhcp server has notes about the "computer" at that MAC address in it's log.
Another option is to set up the printer so it uses wifi and your "email address connection" solution using conman.
