Hi, I'm new and novice user in iRedMail, I just installed "iRedadmin" on my Ubuntu Server 12.04 LTS, I have a domain registered with godaddy.com, my data are:

https://ubuntupower.net

* MX, A, TXT records on godaddy.com:

A (host)
@    201.227.104.52    1 Hora   

MX (Mail Exchanger)
10    @    mailstore1.secureserver.net    1 Hora   
10    @    server.ubuntupower.net    1 Hora   
0    @    smtp.secureserver.net    1 Hora   
10    @    smtp.ubuntupower.net    1 Hora   

TXT (Text)
@    v=spf1 ip4:201.227.104.52 -all    1 Hora   

-my local hostname is server.ubuntupower.net
-10 Priority
-@ Host
-201.227.104.52 is my public IP

* I open ports 22,25,80,110,143,443,465,587,993,995 on my firewall/DSL Módem because I read in another post that was to do
* I have created an email account in iRedAdmin -> christian _at_ ubuntupower dot net

¡But! I can't send or receive e-mails externally, I don't understand where's my problem, please help me

Obviously, you want to use '201.227.104.52' as mail server, but your MX records are wrong.

MX (Mail Exchanger)
10    @    mailstore1.secureserver.net    1 Hora   
10    @    server.ubuntupower.net    1 Hora   
0    @    smtp.secureserver.net    1 Hora   
10    @    smtp.ubuntupower.net    1 Hora

Other servers will send emails to smtp.secureserver.net (smaller number has higher priority). If smtp.secureserver.net is down (cannot reach on port 25), other servers will randomly pick up one of rest 3 servers for mail delivery, because they have same number (10), so they has the same priority.

Right! Sorry
At this time I will change this record

0    @    server.ubuntupower.net    1 Hora   

Now, it's the only MX record. I'll wait to that "godaddy" can refresh the changes and then I will send you a reply, thank you so very much, and sorry for the inconvenience

regards

Maybe caused by greylisting. Does email arrive if you wait for some minutes? If not, any bounce message in the sender mailbox?

Oh man, I'm very confused, I don't understand what happened, but having received 5 mails successfully, I can't more! sad the error message is next:

********************************************************************************************************

I reviewed in http://mxtoolbox.com for some problem, but, the results are positive ... I don't understand

Please login to your MySQL server, you can find one (and only one) record in SQL table "cluebringer.checkhelo", please either delete it and set it's value of column 'disabled' to 1.

Re: External Communication

Cannot sent to external mail servers like Gmail/Hotmail? Any related log in your mail client application (Outlook, Thunderbird)? And any related log in Postfix log file on your server (/var/log/mail.log)?

All SMTP connections timed out.

You must check firewall/router to make sure they don't block port 25, also, ask your ISP to check whether they block port 25 too.

My ISP says they port 25 is NOT blocking, I check my firewall/módem and the port is open, finally I made a test from portchecktool, and the port is open, I don't understand,

Re: External Communication

I can reach port 25 now.

*) Do you still have this issue? Still "Connection timed out" while connecting to port 25?
*) Do you have correct route IP address set on your server? Check it with command 'route -n'.
*) Check firewall on your server again with command "iptables -L -n".
*) Check firewall rules on your network firewall/routers again, make sure they don't block port 25.

It must be something wrong due to your network related settings or restrictions. Please ask support from your network administrator.
