PHPMail (How do the big hosts do it?)

slimx

How is that the major web hosting companies are able to offer websites with phpmail and it "just works".

Whenever I setup a WordPress site, phpmail 99% goes straight to spam. The IPs are not blacklisted anywhere, I have tried multiple providers - even larger VPS providers .

At first I thought it was to do with LiteSpeed, but a CPANEL managed server running litespeed seems to do it just fine too.

What is it that makes the larger web hosting company phpmail executions just "go to inbox". Why do I need to enable SMTP. Am i doing something wrong? Or is this purely around IP allocation - larger hosts get forgiven more?

Soo depends. We are blocking postfix for years. And like a year ago, simply.com started doing this also. This specifically confirmed to me, that this is the right way.

But there are services like amazon ses that is for transactional emails and is trusted, cause they do protections. This is same with other big providers, as we found out.

I thought for a while we could implement this system wide also. But seems useless at the end for us.
