Having problems sending email to a specific domain. It's returning a 550 SPF Policy Framework error saying we're being rejected. There IS an SPF Record set up, and I just verified it through a SPF look up tool: http://www.kitterman.com/spf/validate.html
Exchange is set to use the ISP's (Integra Online) SMTP as a Smart Host for all external mail delivery. Could this be part of the problem with the SPF? There were so many odd delivery problems, using the ISP's SMTP as a Smart Host solved 95% of them.. I'd like to keep using it as a smart host if possible.
It looks like, according to the error, the Exchange server is identifying itself as the .LOCAL domain instead of it's Internet domain.. could this be the problem? The MX record is set up properly and when i telnet into the server via the MX record DNS name, I get the proper FQDN for the external domain..
