Can I forward email from a domain to SPAMCuda instead of having the MX record pointed to you?
No. The reason for this has to do with how SPAMCuda operates – it requires the sending machine’s protocol information to make proper decisions about email messages. If you forward email rather than point an MX record, then the connection comes from the forwarding machine and critical transaction information is lost. Also, any challenges issued would go back to the forwarding machine, which is not what you want to have happen – that’s the wrong place, and would likely cause the challenges and rejections to be silently lost forever. In the worst case it could result in YOU spamming a victim of header forgery. For these reasons attempting to serve a domain’s email in this fashion must not be done, as it will not operate properly and could result in lost email and/or your machine being implicated as a spam source! If you wish to point a domain’s email at the SPAMCuda system, you must point the domain MX records at “mail.spamcuda.net” once you have set up the account(s) from the control pan
