In gmail there is no problem.

Email source from mail-tester.com is

whats wrong with my vps mail server ? Why mails are going to the spam? Need your advice.

Also did some digging and want to make it something like which is quite similar to 2nd mail server(shared hosted) -

1. Received: from localhost (localhost [127.0.0.1]) > Received: from [host-name] (hostname [127.0.0.1])

2. DKIM KEY LENGTH (BITS): 1024 > upgrade KEY LENGTH (BITS): 2048

Can you help me, how I can change these?

Hope many people is suffering from the same problem, but no proper solution couldn't be found in the forum.
Everybody will be benefited with your suggestions.

Thanks in advance.

It's no use you want to show mailtester email, would help just the rejection message from yahoo/hotmail/aol.

These ISP are using ReturnPath, maybe you have low reputation on that blocklist.
You must register for that service, to can deliver mail to that ISPs, here:

https://www.senderscore.org/register/

You are having problems too in your dns blocklists, you are using a public DNS to query them.

Code: [Select]

   *  0.0 URIBL_BLOCKED ADMINISTRATOR NOTICE: The query to URIBL was
   *      blocked.  See
   *      http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block
   *      for more information.
   *      [URIs: jxxextxxhxy.com]

You must to use at least one the three:
1) using your own non-forwarding caching nameserver to avoid being lumped together with other users queries;
2) setting up your own mirror of the DNS-blocklist;
3) or paying to use the blocklist. The choice is up to the DNS-Blocklist administrator.

Regarding URIBL_BLOCKED issue. I saw that most of the emails which are ended in Inbox have the same. You can see that my 2nd domain is delivering mails to inbox which has same regarding DNS query. Hope this is not a problem. Though I'm not sure..

Regarding Senderscore, yes you are right that volume sender class is very low.

I have purchased a new domain and integrated it in the vps. Also I bought the vps last month. Is it really effecting the mail delivery?

Any suggestion?

Thanks...
