Cannot Receive external mail - Postfix, Courier, MySQL And SquirrelMail (Debian Lenny

I followed the virtual domain setup on the forge @ http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny

When I send email from the local server via mailx it works fine and get to the virual user. I can log into SquirrelMail and see the message. However, when I send mail from any outside server it gets kicked with a 550 and the following message:

Generating server: hqpexedg02.admin.cci.edu

[email protected]
p3pismtp01-015.prod.phx3.secureserver.net #550 #5.1.0 Address rejected [email protected] ##

I have gone back throught eh tutorial several times and each of the checks, everything looks good. Can anyone assist?

 

Code:

tail -f /var/log/mail.log

- send another mail ..
- paste the lines that are generated from that mail here.

 

Sent another message. No output in maill.log, mail.err, or syslog.

Same 550 error on bounced email.

 

Sent another email. No output in the mail.log, mail.err, or syslog

 

Please check if the MX record of your domain points to the correct server. You can check that with

Code:

dig mx yourdomain.com

 

Man - you nailed it on the head.

My ever so helpful DNS provider routed my MX record to their mail server. Changed it mine and everything is great.

I should have seen it - Thanks again.

 

Hello sir. I have also followed the tutorial word by word in creating virtual user in CentOS 6.5.

I cannot open my squirrelmail account because I do not have any email yet (as based on the suggestion that the email created should have an email sent so that the email address can be opened during first time).

I wanted to send an email from gmail but my email bounces back. I have tried the "dig" command and this is the output:

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> mx ndtc.edu.ph

I am hoping for a response.

 

Did you followed the tutorial word to word? Did you installed mails and send the the welcome mail to create the account for email address?

Which guide you are following?

I have also send an email from gmail to my account in my domain but according to the maillog, it bounces back to the sender.
