[dnout]

Hi there,

I am getting this error when sending emails to hotmail.

SMTP error from remote mail server after MAIL FROM:<me@me.com> SIZE=2808:
host mx2.hotmail.com [65.54.244.40]: 550 SC-001 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support


Any ideas how I can fix this?

Thanks!

There are many reasons hotmail could reject e-mails. If the server is yours, do you have rDNS, SenderID & SPF records set up? Is the mail server IP on any blacklists? From the server can you telnet to hotmails mail servers?

If the server isn't yours I'd suggest contacting your hosting provider and they should know how to fix it for you!

Hi,

Is me@me.com a valid email id?

Hotmail has very stringent email policies and mails from most of the datacenter IPs are filtered by them nowadays.

You may contact your datacenter/hosting company regarding this.

Two things very important if you send emails hotmail. Setup RDNS and SPF record on the server, Then make sure you have antispam software running with MTA agent. If you still have problem post a ticket with them.

An outright rejection indicates something is not setup correctly.

If you can send email to a different domain (e.g. gmail), please do that and provide the complete header of the email. If you omit any information, please indicate that. The header will have a lot of valuable information.

Is Reverse DNS setup properly? (Remember, the owner of the IP block has to update the Reverse DNS record, and you need a PTR record in your DNS records.

Did you setup SPF properly? Most providers like hotmail will reject/flag mail without SPF. This is added to your DNS record.

Do you use domainkeys? This is not required, but will help.

I would also do searchs to see if your IP's are clean and are not flagged.

If all the above are setup correclty, the header is clean, the ips are clean, and you are still having a problem sending email. I would then contact them directly.
