Postfix and Dovecot continuous problems

Hello and thank you in advance for any help offered. I installed ISPConfig using the The Perfect Server – Ubuntu 12.04 LTS tutorial and most components work and have been very happy. I also purchased the ISPConfig 3 Manual so I must be missing something.

I cannot send or receive E-mail using Postfix/Dovecot. I try sending mail via the terminal, but that also doesn't work.

The following are some errors on the Logfiles > Show Mail Log:

Code:

Jun 8 14:26:37 server1 postfix/smtp[9111]: 6321C22099C: to=, relay=none, delay=188213, delays=188213/0/0/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=mydomain.com type=MX: Host not found, try again)

Other errors include:

Code:

Once again, thank you for any and all help

Did you create an MX record for mydomain.com?

The following is in my DNS Zone settings

Code:

A        localhost.mydomain.com.        127.0.0.1        0        

A        mail.        192.168.1.20        0        

A        mydomain.com.        1.2.3.4        0        // Public IP address

A        www.        192.168.1.20        0        

CNAME        ftp.mydomain.com.        mydomain.com.        0        

NS        mydomain.com.        NS1.NAMESERVER.COM.        0        

NS        mydomain.com.        NS2.NAMESERVER.COM.        0

I appreciate the reply. I'm new to this and appreciate the forum support!

First, you have no MX record. Please create one.

Second:

Code:

A        mail.        192.168.1.20        0        

A        www.        192.168.1.20        0

The dots are wrong - please remove them.

You can either use

Code:

A        mail        192.168.1.20        0        

A        www        192.168.1.20        0

Code:

A        mail.mydomain.com.        192.168.1.20        0        

A        www.mydomain.com.        192.168.1.20        0

Thank you for your attention, after setting up the MX record, now I get the following errors:

Code:

Jun 13 12:25:02 server1 postfix/smtpd[3077]: connect from localhost[127.0.0.1]

Does sending/receiving emails work now?

Falko, thank-you for the follow up. No, it does not work yet. I'm receiving a lot of time-out errors. Here's an example in my Show Mail Log:

Code:

Jun 14 09:16:04 server1 postfix/smtp[30692]: connect to mta7.am0.yahoodns.net[66.94.236.34]:25: Connection timed out

Jun 14 09:16:04 server1 postfix/smtp[30692]: D362B220079: to=, relay=none, delay=221696, delays=221546/0.04/150/0, dsn=4.4.1, status=deferred (connect to mta7.am0.yahoodns.net[66.94.236.34]:25: Connection timed out)

Jun 14 09:20:01 server1 dovecot: imap-login: Disconnected (no auth attempts): rip=127.0.0.1, lip=127.0.0.1, secured

I didn't mention this before but my setup is as the following:

Internet <-> Modem(1.2.3.4) <-> Router with NAT enabled(192.168.1.1) <-> Server1(192.168.1.20)

I also receive these errors:

Code:

Jun 14 10:23:35 server1 postfix/smtp[757]: warning: smtp_connect_addr: bind 1.2.3.4: Cannot assign requested address

Jun 14 10:23:35 server1 postfix/smtp[754]: warning: smtp_connect_addr: bind 1.2.3.4: Cannot assign requested address

Jun 14 10:23:35 server1 postfix/smtp[753]: warning: smtp_connect_addr: bind 1.2.3.4: Cannot assign requested address

I have the ports 25 and 110 open and forwarded to Server1.

Again, thank you for the follow up :)
