Hi Rik,

My advice:

Take out < ip dhcp relay information trusted> from both switches'
trunks, take out <ip dhcp relay information trust-all> from both
switches' global config as well.

3750:
Global config: <no ip dhcp snooping information option>
On trunk port towards 3560: <ip dhcp snooping trust>

3560:
On trunk port towards 3750: <ip dhcp snooping trust>
On port towards the server: <ip dhcp snooping trust>

Ofcourse on SVI VLAN 20 you have the helper address command (not
needed on the int vlan 10 though).

HTH

Else, can you please send a full show run?
