DNS setup for email deliverability

Site is online from 9 years.

Two weeks ago had some problems with hosting, so we switched to another Linux VPS hosting company changing DNS setup.

During the last days some of our emails get:

Remote host said: 550 Requested action not taken: mailbox unavailable

Remote host said: 554 5.7.1 <>: Relay access denied

Remote host said: 550 5.1.1 <> recipient rejected

Specific duties include:

1. Confirm dns settings are correct for our website/server; if not configure dns.

2. Debug email deliverability (may be related to rdns?) or may be related to mail server setup - mail fails too often

3. Verify and explain why some of our emails bounce sometimes (many of them sent to the same e-mail provider), or if our domain is going to be blacklisted

We will communicate via PMB AND via Skype.

We expect professional job, with fast turnaround.

I have managed my own mailservers for several years. I mainly use exim, but also have experience of other software. What mailserver do you use? I believe this is unlikely to be a DNS problem, but can easily check.

the information that you have provided makes me doubt that the problems are with your DNS setup therefore your setup will require more in depth investigation hence the timescale and cost i have been an IT tech More
