Hi Martijn, Ciphermail is our SMTP server and is used with DLP to encrypt outgoing messages. The system is authorized to relay messages through this server. I place a debug line in postfix - this is the output. (I cleaned out some of the other match_hostaddr from the list)

Any ideas where to > look? So this is for incoming connections?, i.e., from a remote SMTP to the CipherMail gateway? The SMTP part of the CipherMail gateway is handled by Postfix. Is there more information from the logs? Can you check the logs on the other system?
