Debian + Postfix problem

[voiteck]

Hi, I have problems with receivingemails.
I've installed Debian using this tutorial: http://www.howtoforge.com/perfect-se...ze-ispconfig-2
After installation i've created mailbox (webmaster@maindomain.com) in ISPConfig.
To be precise i've create two account, one in Email Accounts tab and another one in Fetchmail tab, both with same username/password.

Now i'm able to send an email using SquirrelMail to my gmail account:

Bellow are headers from test email (from webmaster@mydomain.com to my.mailbox@gmail.com)

PHP Code:

The problem is, that server isn't receiving emails. When I send an email to webmaster@mydomain.com from gmail i get response from server:

PHP Code:

This is the mail system at host mydomain.com.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                  The mail system

I've checked mail log, and found there one error and one warning:

PHP Code:

Can you post your /etc/postfix/main.cf?

Please make sure that your domain's MX record points to the correct server. You can check it as follows:

dig mx yourdomain.com

Hi, thanks for your answer.

here is /etc/postfix/main.cf

First, you don't have an MX record, so you should create one.

Jul 12 11:13:45 magn postfix/trivial-rewrite[3421]: warning: do not list domain mydomain.com in BOTH mydestination and virtual_mailbox_domains

This means you use a domain in the MySQL database that you have in mydestination as well (magn.es maybe?). Please remove the domain from the mydestination line in /etc/postfix/main.cf and restart Postfix.

[voiteck]

Man, you're great. It's working now, after removing mogn.es from mydestination in /etc/postfix/main.cf

Could you please take a look at dig mx results, i've parked domain at another provider and set up some new dns records

PHP Code:

; <<>> DiG 9.7.3 <<>> mx magn.es
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61000
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;magn.es.                       IN      MX

;; ANSWER SECTION:
magn.es.                86400   IN      MX      1 magn.es.

;; Query time: 87 msec
;; SERVER: 8.8.8.8#53(8.8.8.8)
;; WHEN: Fri Jul 15 01:37:11 2011

Thanks again

The MX record is fine, provided that

dig A magn.es

shows the correct IP.
