Yeah, I get this and had changed servers a couple of times over the years and sought to have shared IPs verified, etc, but I just got fed up of jumping through hoops, despite doing everything 'right'.

I still host my personal email address, but I lost a few jobs sent to my work address by inadvertently being 'rude' in not responding to cold emails from GMail addresses I had in fact responded to. THAT was the situation that really irked. Such a stupid logic, or lack thereof.
