Hi,
I have problem with sending an email from heliohost mail to gmail it gets rejected. I have SPF and DKIM set up. Any ideas how to solve this?
Message I get from undelivered mail:
host gmail-smtp-in.l.google.com[142.250.141.27]
said: 550-5.7.1 [64.62.151.106 19] Gmail has detected that this
message is likely 550-5.7.1 suspicious due to the very low reputation of
the sending domain. To 550-5.7.1 best protect our users from spam, the
