Port 25 is open on ISP, Modem, and router. Postfix appears to be configured correctly. Form mail will delivery mail to address on server. Can delivery mail from one domain name to another on same server, mail will forward to outside address on different server. (Configured in ISPConfig 2 to forward to different email address.) However, I cannot send or receive email to outside address. This had previouslu been working.

I have worked on this issue for days. I think it may have something to do with MX records, but do not have the knowledge to fix and I have read everything I can find. Thanks in advance for your time.
Can you check here if your server is blacklisted? http://mxtoolbox.com/blacklists.aspx Do you have a dynamic IP? You can check if your MX record is correct like this: Code: dig mx yourdomain.com
ISPCnfig 3.0.3 and Postfix Hi Falko. I have installed ISPConfig 3.0.3 successfully in a single server, my public IP is dynamic and of course I am getting : (delivery temporarily suspended: connect to servessserver1.example.com[63.251.179.17]:25: Connection timed out) [email protected] after set up a web with elgg, thanks to your "HOwto..." my dig command for my domain is: :~$ dig mx example.com ; <<>> DiG 9.6-ESV-R1 <<>> mx example.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 35711 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;example.com.

Am I right? Are there other solutions? thank you for your attention and your good job

I keep reading everything about MX records and I must be missing something for I don't really understand especially SPF. The only thing that I have found is that Clamav is out of date to lastest version.(have a fear I might break something and I wish to work on one problem at a time) I would give root access to you via of PM if you would like. I have tried every test I can find. I try very hard to search the forums and Google everything prior to making posts. I am really lost this time. The mail issue is very important to me. I want to thank you for answering posts on this forum, it is difficult to answer questions from those of us that have limited knowledge and when we do not use correct terms. It appears that port 25 times out. I can send mail from the terminal. Mail had worked until recently....I cannot find any errors in the maillog, that is why I was thinking it might have something to do with MX records, also checkDNS.net states timed out. If someone would ever show me exactly how MX record are to work in ISPConfig then I think I would understand. I think many others are as confused as I. I have followed you posts on the subject, but for some reason I don't fully understand.
Is this site the only issue? It doesn't accept connections from me, either. In this case, the issue is at their end. That is the nameserver that is answering your dig query. Probably your ISP's.
My problem is that I cannot send and receive mail. I have tried to find something wrong or an error and the only thing that I have found so far is the mail server times out. I cannot figure out why it times out..... Thanks
falko, this thread is difficult to follow. Had previously answered above questions in this thread. I think I may have found something that is causing mail not to send and receive. Is this my problem How do I fix if this is my problem? I really appreciate the help I've worked for days on this issue/
I can't connect to that server either, so it's a problem at their end: Code: server1:~# telnet 217.20.163.8 25 Trying 217.20.163.8... telnet: Unable to connect to remote host: Connection refused server1:~#
faiko, I appreciate the reply. I am unable to send and receive email from our server. I have tried everything I can think of. I'm quoting this again ...is this the problem that is causing mail not to send and receive: Is this my problem? I apologize for asking the question again. Edit: ADDITIONAL If an email is sent to a domain name on this server and that domain has forward to an outside email address configured in ISPConfig it will forward that email to an address outside that resides on another server, however if squirrel mail is used to send an email to an outside address that email is never sent. I can send mail via of terminal to an email address on server, however I cannot send an email from outside address to server. I have worked on this issue for days, hour after hour....I hope someone will really offer some insight here. Thanks for you time.
No. Have you tried to send to different email providers, e.g. Yahoo email addresses, Gmail email addresses, Hotmail, GMX, other email addresses? Do none of them work, or do some work and some others not? Please check if the MX record of your domain is pointing to the correct server. You can check that as follows: Code: dig mx yourdomain.com
Have tried sending to hotmail, and several others. Have also tried sending from hotmail and another account I have. I get Delivery status notification saying things like Delivery to the following recipients is still underway after 49.3 hour(s): I appreciate you help.
The problem seems to be with your DNS servers. I can't query anything about your domain designoutput.net. It looks like your glue records point both ns1.designoutput.net & ns2.designoutput.net to 173.8.81.81 (you really should have two different nameservers, btw). That IP doesn't answer queries for your domain - at least not from external sources.
I'm also having trouble resolving the domain. This might help: http://www.intodns.com/designoutput.net
Marty, I really appreciate the reply. We had took the server offline and totally rebuilding. We were running an older core Fedora 8 and it was time to upgrade. I was very aware that something was causing a problem on port 25, I just didn't have the knowledge to fix. Hopefully this problem will be resolved on our new build. Thanks for giving up you time to answer question on the forum
