Postfix and Dovecot continuous problems

[keen]

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:

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:

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

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!

[falko]

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

Second:

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

A	mail	192.168.1.20	0	
A	www	192.168.1.20	0

or

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:

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

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:

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:

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

Is that a remote server or your own server?

Can you post your main.cf?

What's the output of

netstat -tap

?
