Hi, I recently set up sendmail to serve as a relay server for inbound email
external email ---> sendmail server ----> corporate server
the sendmail server seems to work fine, but one domain (xyz.com) gets its emails bounced with the error of "550 Message rejected because SPF check failed". the person sending mail from xyz.com **can** deliver mail successfully to gmail and hotmail accounts, so the problem appears to be on my end.
If I look at the spf records online for xyz.com (e.g. using an spf tester like this-> http://www.kitterman.com/spf/validate.html
) it says that the the IP address that my sender is sending from is valid.
Are there any simple ways to disable spf checking on my relay server? Or other ways around this?
