cannot send any emails to gmail

Postby colouredFunk » Tue Feb 20, 2018 8:45 am

I have an IIS server with multiple domains, multiple clients all many mailboxes. All of them are starting to fail when sending mail to Gmail accounts. with bounce-back and 550-5.7.1 error.

I've tried adding the following SPF to the domain DNS details -
"v=spf1 ip4: ip4: ~all"

No idea what else I can do.
