Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a client's website e.g."aaa.com" hosted on my VPS with Plesk installed. The client manages the domain and he just set up an A record for aaa.com pointing to my VPS server.

The website works fine. However, if any email sent from the website, it doesn't go out of the VPS server. I mean if an email is sent to info@aaa.com (for example), it is not delivered to the client's mail server. When I look into info@aaa.com which has been set up on my VPS, all the emails are just there!! Even if I delete this email on my vps, my client's mail server still doesn't receive any emails from the website.

It sounds like a DNS issues, but the client doesn't use my DNS, he purely hosts the site on my server.

Can anyone please help me out?

This question came from our site for professional and enthusiast programmers.

Sounds more like a mail transfer agent issue. And should be moved Server Fault I think. –  beetstra Jan 28 '11 at 0:07
Are MX records setup correctly; can you get the logs from the server which will help find the problem? –  Jacob Jan 28 '11 at 3:59
Can you show us any relevant logs from /var/log/syslog? Is your provider blocking outbound TCP port 25? –  bahamat Jan 29 '11 at 21:14

If they have their own mail server, then you need to change the MX record for aaa.com to point to their mail server.

When no MX record exists, then the A record is used. That's why mail is going to your server. You probably want to turn off the smtp server if you don't need it.

Simply turn off the mail service for that domain.

Click the domain, then the "mail" drop down then "mail settings", and untick "Activate mail service on domain"
