The SMTP does not support your model to use your "green" server to "pull" mail from the DMZ server. It is a "push" type communication model. So you have to use something like - pop protocol to transfer the mail (e.g. fetchmail) - nfs/ftp to periodically transfer the mailbox files - use cron to peridically allow incoming smtp on the firewall and initiate a resend on the DMZ mailserver Peter
