I've searched and found a couple of threads here asking the same question but no proper solution. Mostly these threads were a few years old so I am starting my own here.
Basically I have clients hosting their emails with me that need to comply with certain regional laws which means 100% reliable storage of all incoming/outgoing emails. Lets not worry about how I back this up, for now I only need a solution for archiving.
My base system runs ISPCFG3 with Debian Squeeze.
Nice to have features:
- archive all emails, incoming and outgoing on a per email domain basis
What I have found so far:
- web interface for searching and restoring from the archive into the original location
- CLI for restoring from the archive into the original location
To be honest, the seemingly easiest solution from the ones I listed above seems to be this one: http://www.arschkrebs.de/postfix/postfix_archive.shtml
but I admit I don't completely understand it.
Does anyone here have a similar solution in place and is willing to share the details?
