Hello all,
I am looking for a way to relay from one internal postfix box to another internal postfix box using TLS. Basically, I have several servers with applications that need to relay HIDS events and system logs etc. to the central postfix email server for normal distribution from there. Right now, using the relayhost parameter with addressing to the central server works nicely. But due to the sensitive nature of the information contained in these emails I do not want them to be passed "in the clear", nor do I want any credentials passed "in the clear". The central mail server already uses TLS and SMTP AUTH (Dovecot SASL) for the typical mail clients for end users to connect to securely receive email. Can someone please point me at a good piece of documentation or a how-to that demonstrates the proper way to relay while using TLS? Thank you very much. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
