DKIM both 550-5.7.26 do not pass).
CONFIG_TEXT: Reason: 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 [example.com] 550-5.7.26 did not pass with ip: [203.0.13.2]. The sender should visit 550-5.7.26 https://support.google.com/mail/answer/81126#authentication for 550 5.7.26 instructions on setting up authentication.

I added SPF and default DKIM record in DNS but not working
I've yet this record, and not work. Have you a solution??
MD Rashed Bin Kuddus and William Apa Hello,
If the SPF and DKIM DNS records were added on the Registrar side (externally hosted DNS Zone) of the domain and the issue persist even after the normal DNS propagation times, please consider creating a Support request for further analysis of each situation.
Thanks
still the same problem
