SPF mails being received when they are sent from the correct company

Posted on 2006-12-01

I have a problem where emails are being sent out as but the server when first installed is  The emails users are sending are being eith blocked or added to spam and reported Sender is forged (SPF Fail).  The server is a 2000SBS that has exchange 2000 server.  I'm guessing that this is caused as the server is send as and is seen as SPF, so is there any way around this?

SPF records are maintained by that company. If their SPF records don't match their current email setup (smtp server is not included in the SPF record), that is their fault and they need to change it, not you. The actual domain name really doesn't matter with SPF, it's all about the IP addresses the mail comes from. So the .com or doesn't matter.

Thanks jar3817

So who do I tell that the customers IP address is now going to be sending the address?  I guess the ISP?

well who ever runs the dns for the domain. If the email is going to come from than the people that run the dns for need to add the IP address to the SPF record for that domain. They would be the ones to tell. That might be the people at that company or it might be their ISP, depends on their setup. I would give all the info to the company and let them deal with it.

You have been a great help.  We have contacted the ISP that holds the Domain and they have confirmed that we need to update the SPF record for the domain.
