[Cialug] Email Archiving

[j.bengtson at mchsi.com]

Is it possible to configure a firewall to forward the email to a proxy server, which would then forward the mail to your mail server, and also to send a copy of the message to another archive email server?  That way the email is handled as per normal, but a copy of that email is sent to an archive email server that does nothing but store that copy (only sysadmins could access the archive server, and such access would be heavily logged).  The firewall would have to be configured to bounce a copy of outbound emails to the archive email server as well, giving you a complete archive of all inbound and outbound email.  I'm not sure if it could be set up to archive internal-only emails...

I don't know if such a system exists, or even if it's possible, but if the firewall or proxy could be configured like this, you'd have what you're looking for.  Alternatively, there are some open-source email archive systems out there: http://www.mailarchiva.com/features.htm

Interesting, .. thanks!! The architecture is similar to the 
fetchmail, however, in that an email could be deleted on the hosting 
service in between 'archive' events.

The more I think about it, it almost has to be integrated with the 
physical mail server (or a proxy thereof), .. but the other side is 
merging that incoming archive with outbound email archives.
