Mail Delivery Issues

Hi everyone!

Just migrated our server from Sydney to Los Angeles.

Everything has worked so far however we’re having issues with mail delivery with Outlook & G-Mail.

I tested the IP through MX Toolbox, everything was good, I noticed the IP was blocked with Trend Micro.

When I do a diagnostics check with MX Toolbox once again.

I notice it mentions

554 5.7.1 Relay access denied [938 ms]

How can I improve deliverability to Outlook & GMail?

I’ve already re-run sudo mailinabox



This is my current SPF record

v=spf1 mx a ptr ip4: ?all

and the hostname is

Hope this helps!

Also a note!

I’m unable to login to Google Postmaster Tools as ‘my domains does not satisfy Googles security requirements’
