I Would like to know if it's possible to chain perdition server between them. For example I have some server on my LAN who have to POP some gmail box. In order to secure the access I would like to install two perdition servers : the first one in the LAN and the second one in DMZ (Server->Perdition_LAN->Perdition_DMZ->Gmail server).

I have successfully installed the server on the DMZ and it works, but when the one the LAN try to reach it, Ive got the following message  : 

I've got the same configuration on the two server except the outgoing_server, and I'm using POP3S with self signed certificate.

Can you help me please ?

Thanks !

Aurélien.
