Microsoft/Hotmail forgot to set reverse DNS pointers?
Today I received some notices about Hotmail users who couldn't send e-mail messages to various receipients due to spamfilters blocking them at the receiving mailservers. Seems like Microsoft/Hotmail staff forgot to set some reverse DNS pointer records: Diagnostic-Code: smtp;450 4.7.1 Client host rejected: cannot find your reverse hostname, [157.55.1.150] (Verified this using various public DNS servers, to exclude potential local issues) Anyone here who has proper contacts to give them the clue-bat? -- Michiel Klaver IT Professional

noc@microsoft.com will probably understand or at least point you in the right direction. ~JasonG

Yeah, tried that, doesn't work. Same for moc@ and soc@ <noc@microsoft.com>: host mail.messaging.microsoft.com[216.32.181.178] said: 550 5.4.1 noc@microsoft.com: Recipient address rejected: Access Denied (in reply to RCPT TO command)

I gather the correct eyes are on the problem and it should be resolved soonest. Thanks for the heads-up. Aloha, Michael. -- "Please have your Internet License and Usenet Registration handy..."
