Hi Everyone
About 10 days ago, seemingly random emails passing through my Email Security.cloud service started getting rejected by my mail service provider. The error message is 550 5.7.23 <email address redacted>: Recipient address rejected: Message rejected due to: SPF fail - not authorized.
My SPF record is correct and in place and my mail provider seems to have absolutely no idea how to resolve this.
Any ideas?
Thanks.
