Hi,

I using oscommerce for over 3 years under one domain with cloud server. everything runs perfect until 2 months ago. All hotmail customer stop recieving emails (yahoo and gmail works fine). However, I can send email though outlook from my own workdesk.

I went online and trying to find what the problem it maybe, it turns out I may need to config the Sender Policy Framework.

So, here is my problem.

My domain currently in host under 1and1.com, and the name server is not under my control panel. So, I only can change one of the mx record to my own domain, but the backup mx record always 1and1.com.

Base on my understanding, in order to config the sender policy framework, I need to add a txt record under DNS setting. In order add the txt record; I need my domain name server point to the same server. (if I am wrong, or has alternative way to do it, please let me know.).

Change my nameserver to my own server is the last option I want to do.

Are there any other solutions for the problem? Any suggestion is appreciated.

thank you

I suggest you contact 1and1 and ask them to send a request to Hotmail to have their mail servers removed from the 'blacklist'.  A good hosting provider would have already done this as soon as they noticed the problem, in fact hosting providers are forewarned when an online mail service intends to block thier mail servers.  I personally don't think you should have to reconfigure your MX records and transfer relays to correct the problem, that is what you pay your hosting provider for.

Hi chris
I don't think my domain in the blacklist, because I can send email though outlook, and I also can send email though 1and1.com online email program.
so it doesn't looks like something to do with the blacklist. the other reason I can think about it maybe relate to ip address.

Ken,


Online mail processors use Mail server IP addresses to block mail servers entirely from sending mail.  I went through this about 4 months ago with Godaddy and it took them 3-4 weeks to get the IP address removed from the blacklist.

<tjskids@hotmail.com>: host mx4.hotmail.com[65.55.37.120] said: 550 SC-001
    (COL0-MC4-F30) Unfortunately, messages from 74.208.213.66 weren't sent.
    Please contact your Internet service provider since part of their network
    is on our block list. You can also refer your provider to
    http://mail.live.com/mail/troubleshooting.aspx#errors. (in reply to MAIL
    FROM command)

so same email can go though outlook and 1and1.com mail server, but not though my own server.

I think it can be something relate to ip address.
