Hello! I did an evaluation for sysadmin purposes of an Ironport gateway. On Mar 30, 2006 at 1659 +0200, carlopmart appeared and said:
somebody knows which software for MTA, anti-spam engine, etc IronPort use?. I find that antivirus is sophos.
Antivirus engine is Sophos. The MTA is their own. They developed an high-performance MTA for AOL and use it in their appliances. The antivirus engine is either Symantec Brightmail or again their own antivirus engine.
- AsyncOS kernel supports more than 10,000 simultaneous connections. Is this right? Linux and BSD kernels doesn't support this "feature"?
AsyncOS is vere capable and can handle such load. It depends on the hardware though. AsyncOS is based on *BSD; Linux and *BSD can handle similar loads if configured properly.
- "IronPort also developed a high performance file system and an I/O driven scheduler optimized for the asynchronous nature of messaging". Is this high performance filesystem based on UFS2, ext3, reiser, ... etc or a new type of filesystem?
I have no information about their filesystem.
- "For example, 1000 threads,each with a 1MB stack, would consume 1 GB of RAM! [...]" Really??
I think you might have to try it. I believe that the system uses load limits when under pressure, but we didn't test that.
