Not so much of a technical issue, but was wondering how long everyone keeps their message tracking and/or e-mail logs around? We use an M-Series, and it looks like you can't specify retention time, rather, you have to manually configure your disk size to limit or increase the amount of data you're keeping.
I'm curios what other folks are doing, how long they're keeping message tracking data available and/or if they have an overall e-mail retention policy. I know some firms are under government guidelines to archive all electronic communication for 7 years or similar.
Thanks.
