Can someone please shed some light on what this means?
I get the following error in the exim_mainlog:
2016-01-06 10:59:12 H=s30.spamh.com [66.135.37.10]:55726 I=[1.2.3.4]:25 X=TLSv1.2:DHE-RSA-AES256-GCM-SHA384:256 CV=no F=<[email protected]> rejected RCPT <[email protected]>: SPF: 66.135.37.10 is not allowed to send mail from sender.com
I'm thinking this means that the SENDER has set a hard-fail for the SPF. And since e-mail is sent from a 3rd party anti-spam filtering service, Cpanel is saying, "spamh.com's IP address isn't on the list so i'm hard-failing".
Is this correct? In which case, if any of our clients use a 3rd party filtering service, doesn't this mean we have to either WHITELIST their IP address or disable SPF checking?
It's not very reasonable to tell every potential sender to "change your SPF to a soft-fail". Or am I missing something?
Thanks,
Lawrence
