I have spent the past 8 years working at a small ISP, where I manage E-mail, DNS, Web, and Voip servers for a couple thousand clients.

comment limitation of sent messages in exim
What are you trying to do? Are you trying to limit the amount of spam that gets sent through? There are other, better ways of doing that. Are you trying to limit the number of messages sent by your legitimate users?

comment What are the recognized ways to increase the size of the RAID array online/offline?
I think this is an important question. Yes, it may be too broad, but the answers so far are indeed helpful for anyone who hasn't done this before.

comment Network errors. What is at fault here?
OK, I found the statistics detail somewhat illuminating. One port has seen 34K Rx drops since rebooting 7 days ago, for example.

comment Network errors. What is at fault here?
Oh, diagnostic information like that would be gold wouldn't it? No, instead this switch gives me a table with a count of send errors and receive errors. Even the system log doesn't have any actual error messages.

comment Network errors. What is at fault here?
We have 3 APC Masterswitches that run at 10Mbps half duplex, but they're not the ones generating errors. Most (7 out of 15 devices) are Gigabit ethernet adaptors on Dell Poweredge servers, and the rest (5) are 100Mbps full duplex.

comment High-availability system, how do I start?
Ugh. Yes, that's fine if you're Sony. If, on the other hand you work at a company where you're the sole administrator, the likelihood of someone being interested in anything more interesting than your e-mail passwords for spam is actually extremely low, and the creative effort put into malicious activity hardly rises above the script kiddie or 419 scammer level. The bigger threat to the network is that one sysadmin, by a factor of about 100x.

comment How to build a high availability Postfix system?
I think that a NAS basically solves the problem of mail storage and syncing, doesn't it? Especially if your mail store gets Large and you're hosting mail for numerous domains.

comment High server availabilty for a small business
Actually, I suspect "30 minutes" is tied directly to the number of customer complaints he gets in 30 minutes. Failover systems for purely TCP/IP applications aren't so hard. Failover systems for telephone systems or VoIP that has some kind of tie-in to the PSTN on the other hand, are egregiously expensive.
