Easier if you paste a sample bounce And check if you have some kind of smtp capable firewall device (like a barracuda) or maybe an outsourced filtering provider that's filtering this lot before it reaches your mailserver. srs !SIG:47f49fcf285637219712276!

Contact at mfa.gov.cn?
by Christina Klam 03 Apr '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Does someone have a contact name at mfa.gov.cn? When one of our users tried to send an email to a host at mail.mfa.gov.cn, we discovered that we are being blocked by mfa.gov.cn. From my gmail account, I have sent multiple emails to the contacts listed in APNIC. But, no one has responded. Moreover, when I sent an email to postmaster(a)mfa.gov.cn, the email bounced as that mailbox does not exist. If someone has an IP range of 192.X.X.X, can you see if you see if you can get to mail.mfa.gov.cn? At this point I do not know if someone fat fingered a RFC1918 ACL & is blocking 192.168.0.0/8 instead of 192.168.0.0/16, or if they are blocking us upon our AS number (26099).

Hotmail NOC Contact
by Jason J. W. Williams 03 Apr '08

Hey All, Does anyone have a good contact number for the Hotmail NOC? We've got e-mails from Hotmail to some of our customers being returned the Hotmail sender with a 554 error message fairly regularly. Our logs aren't showing any rejections, so we need to talk to Hotmail and find out what the 554 means on their side (there's no error description). Any help is greatly appreciated. -J ________________________ Jason J. W.

Moving enough air to cool >400 (or, in your case, 2000) watts per square foot is *hard*. It depends on where you are located, but I understand what you are saying. However, the space is the cheap part. Installing the electrical power, switchgear, ATS gear, Gensets, UPS units, power distribution, cable/fiber distribution, connectivity to the datacenter, core and distribution routers/switches are all basically stepped incremental costs.

Similarly, to a customer, all they care about is getting >their gear online, and can care less whether it needs to be in 1 rack or >in 5 racks. I don't disagree with what you have written above, but if you can get 100A into all 5 racks (and cool it!), then you have five times the revenue with the same fixed infrastructure costs (with the exception of a bit more power, GenSet, UPS and cooling, but the rest of my costs stay the same.) >To rephrase vijay, "what is the problem being solved"?
