As often as necessary. They'll keep growing until you do a successful backup, at which point they will be purged. Everything that your users do gets written to the log files and then gets committed to the database. So, your users are generating 5 MB worth of changes every 5 to 10 minutes.
As for your other questions, here are the answers: 1. Probably. 2. If this is abnormal behavior, possibly. 3. You can start by looking at your tracking logs. 4. I don't think so. 5. Read the FAQ.

Our Exchange server appears to write a new 5mb log file every 5 to 10 minutes. I searched the FAQs and Archives but did find an answer. Here's our system. Single Server Exchange 5.5 SP 3 NT 4.0 SP 5 550 users Is this normal? Is this a Mail Loop? If so how can I find it? Is some one relaying mail off my server? If so how can I stop it?
