This article refers to the Barracuda Message Archiver firmware version 5.0 and higher, and Unix mail servers including Apple Mail Server, Sendmail, Postfix, and qmail.
You can configure Sendmail, Postfix, and qmail to forward a copy of all incoming and outgoing messages as a blind-carbon-copy (bcc) to your Barracuda Message Archiver IP address. Sendmail, Postfix, and qmail support most Unix operating systems including Mac OS X.
The Barracuda Message Archiver IP address should be in the form archiver@<IP>, where <IP> is the IP address of the Barracuda Message Archiver. On some mail servers you may need to encapsulate the IP address in square brackets (ex:
qmail provides a copy of each mail message that it sends or receives through the QUEUE_EXTRA code. Install a qmail tap patch to send these copies to another email address (in this case, archiver@<IP>).
For Postfix, use the configuration parameter always_bcc to forward a copy of all incoming and outgoing messages as a bcc. For more information, see Postfix Configuration Parameters.
