Whenever we try to send emails to anyone with a Gmail account it get kicked back to us with this message:
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
SMTP error from remote mail server after end of data:
550-5.7.26 This mail is unauthenticated, which poses a security risk to the
550-5.7.26 sender and Gmail users, and has been blocked. The sender must
550-5.7.26 authenticate with at least one of SPF or DKIM. For this message,
550-5.7.26 DKIM checks did not pass and SPF check for [***.co
550-5.7.26 m] did not pass with ip: [18.104.22.168].
I have looked at the couple of similar questions/answers that I have found on the community forum but, I’ll be completely honest, I am a COMPLETE novice this issue is way beyond my understanding and completely over my head.
I don’t understand this. We are a small church who barely sends out any emails? Could it be related to our email server? We are in the process of moving away from them because they are junk. (Homestead .com)
Note also that the SPF record (when corrected), includes a whole /18 range.
That’s 2**14 (16384) distinct IPs, where the actual MX (assuming that the MX is also the one sending e-mails out) resolves to 3 different IPs.
You should also investigate why the DKIM checks did not pass, as it may imply that your server is seriously misconfigured.
Thank you for taking the time to look at this. I have repeatedly been in contact with our mail provider about these issues and they went from saying they were working on it… to completely ignoring anyone who is having this problem. It is a widespread issue with our mail provider (their community forum is about 75% complaints just about this issue) and it’s been going on for almost a year. We are in the process switching our web host/mail provider, etc but in the meantime I was hoping we could at least resolve this one issue.
I have not fixed the SPF record because, as I stated above, I do not understand this AT ALL and have no idea how to do it. I see there is a SPF wizard link on my dashboard but I do not even know what to put in the fields that it asks for. I apologize for my lack of knowledge but it is what it is… lol
