So, I have an IBM x3500 M3 server running in my house (yes, overkill but I got it free). This server has a hardware management system with an Ethernet port that runs independently of the OS (IBM RSA-II). I can access this management system even if the server is powered down. I can use it to check the status of hardware, power the server off/on remotely, schedule power ons and do other nifty things. One really neat thing is it can send an email to me if there's a problem, or if I just want status updates on a schedule I set up. Now here's the problem: it uses an SMTP server address to send the email, but it does NOT support authentication. I tried using Google's SMTP server, but those are not open and require a username and password. So that won't work. I searched the interwebs for free & open SMTP mails servers and did turn up with much. I could just setup a simple SMTP server on the server itself, but that won't help me if the server is down and the RSA-II is needing to send the report. I'm about to toss 5 2TB hard drives in a RAID-5 in this server and the RSA-II will monitor the status of the drives and alert me if the array drops into a degraded status, so I want this to work. Any idears? Thanks in advance.
