Unable to receive mail (ISPConfig 3)

Unable to receive e-mail (SquirrelMail) also e-mail message does not return back to sender. However, I can send e-mail without problem.

I've got errors/debugs from ISPConfig3 Log

Error: Possible security violation when deleting the maildir:
Debug: Possible security violation when deleting the maildir:

I'm running
The Perfect Server - CentOS 5.4 x86 [ISPConfig 3]

Any ideas how to fix this problem?

Thanks

Thanks very much for your reply.

I do have a MX record in my DNS looks like this

MX mydomain.net. mail.mydomain.net. 10

I have another server running perfect server centos 5.3 with ISPConfig 2 plugged into the same router, firewall is disabled for my static IPs I can send & receive email from any domain.

Would you have any other suggestions what to check?

------------------
Perfect Server CentOS 5.4 with ISPConfig3

 

Do you have an A record for mail.mydomain.net that points to the correct server?

Do you have more than one public IP?

 

I think so, see attached screen shot of my DNS records. Am I missing anything?

Yes.

Perfect Server CentOS 5.3 with ISPConfig2 has 1 public IP (xx.xx.145.50)
Perfect Server CentOS 5.4 with ISPConfig3 has another public IP (xx.xx.145.49)

*green marks on screen shot are replacing mydomain.net.

Thank you very much for your assistance.

 

Is it possible that your ISP blocks port 25 on the xx.xx.145.49 IP?

 

I just called my ISP and they aren't blocking any ports. My router has firewall disabled. How could I check firewall settings on my "The Perfect Server - CentOS 5.4 x86 [ISPConfig 3]". Do these Firewall setting look OK?

Ok, here's the problem:

Code:

tcp        0      0 [COLOR="Red"]127.0.0.1[/COLOR]:25                0.0.0.0:*                   LISTEN      3749/master

Postfix is listening on localhost only. Please run

Code:

postconf -e 'inet_interfaces = all'
/etc/init.d/postfix restart

 

I wonder if I missed above part when following steps to setup "The Perfect Server - CentOS 5.4 x86 [ISPConfig 3]"

I ran command below and it looks like my issue "(10): Connection refused" is fixed

Code:

postconf -e 'inet_interfaces = all'
/etc/init.d/postfix restart

Right now, I am getting another error message when trying to send from my gmail.

Code:

Would you know how to fix "554 554 5.7.1 - Relay access denied"?

Thanks for your help.

 

Any errors in your mail log?

 

Here's the latest from Mail Log, any ideas?

I'm still getting "Delivery to the following recipient failed permanently"

Code:

Any suggestions how to troubleshoot above issue?

Thanks.

 

Does the MX record for your domain point to the correct server? You can check that by running

Code:

dig mx yourdomain.com

 

I ran dig mx mydomain.net and my result I believe is correct, because when I run the same command on my other server with ISPConfig 2 it returns same result.

Code:

[root@designer ~]# dig mx mydomain.net

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> mx mydomain.net

Does anybody know what else to check for error:

Code:

550 5.1.1 : Recipient address 
rejected: User unknown in local recipient table; 

Thanks!

 

And does mail.mydomain.net point to the correct IP? What's the output of

Code:

dig mail.mydomain.net

?

 

Thanks Falko. Yes, mail.mydomain.net does point to my server ip address

Code:

[root@designer sites-enabled]# dig mail.mydomain.net

Do you have any other suggestions?

Ok, then this means that the email account isn't existent on the server. Did you create it in ISPConfig?

 

Hi Falko, Thanks for your response.

Yes, I did create email in ISPConfig. I tried again, I deleted that email & domain and recreated again in ISPConfig.

In ISPConfig3 to create an email account, I clicked on E-mail tab (on the top) then:

1) I clicked on Domain (from left menu)

a) Add new Domain
b) I entered domain name (mydomain.net)
c) Save

2) Click on Email Mailbox (from left menu)

a) Add new Mailbox
b) Entered Realname
c) info-x for Alias change in drop down to mydomain.net
d) entered password
e) spamfilter (not enabled)
f) enable receiving (cheked)
g) Save

Does this sound correct on creating email account in ISPConfig3?

How can I check my account exists? I think my account exists, since I can send email from that account to my gmail account using squirrelmail, however when I send message from my gmail account to [email protected] I still get the following:

Code:

The error that the other server returned was: 
550 550 5.1.1 <[email protected]>: Recipient 
address rejected: User unknown in local recipient
table (state 14).

Would anyone know what else should be checked?

Thank you,
Onastvar
