cannot send any emails to gmail

Post by 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 ip4:11.11.11.11 ip4:11.11.11.11 ~all"

No idea what else I can do.
Thanks

Hi,

Your IP address is blacklisted. Please see: https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a108.60.201.34&run=toolpage

This would be a contributor as to why Gmail is rejecting your messages. You need to navigate to the blacklist provider website to gain more information why your I address was blacklisted and request removal.
