RE: NetBSD/Postfix

Hi Matt,

I think the concern is more about hackers breaking into the system and being
able to grep info from the files as mail flows through the system. The disk
encryption I think is only really a win if the physical volume is stolen?

would like to use NetBSD for part of this solution. The solution involves
the intake and processing of large volumes of email. Due to some customer
requirements /gov't regulations the incoming spooled mail files need to be
encrypted when on disk. Is it possible to setup postfix, or I guess
sendmail, to encrypt it's mail files (like /var/spool/mqueue from my
sendmail days) when they are stored on disk before being forwarded to
another machine?

messages are dissected and processed.

Would using cgd be a solution? (e.g. encrypt the whole disk)
