Unable to send/receive email from Outlook Express

Which distribution do you use?
The installation of Courier is mentioned in most of the "Perfect Setup" tutorials on HowtoForge.

 

I am using the FC4 and followed the The Perfect Setup - Fedora Core 4. I checked the Perfect Setup SuSe and that has a section describing Courier-IMAP/Courier-POP3 setup and this section is not there in the Perfect Setup FC4. Please let me know what changes that I need to make,if tehre is any, on the exisiting system prior to the installation of Courier-IMAP and Courier-POP3.


Thanks,
Piyo

 

Unfortunately, on Fedora, there are no Courier packages available, that's why that section is missing in the Fedora tutorials...

 

Thanks for the information. I have tried several things to debug the problem in sending mail with outlook and has no success. one thing that i noticed in the maillog is the following error message

Jan 9 02:45:42 ns1 postfix/qmgr[10354]: CA8239B010E: from=<[email protected]>, size=754, nrcpt=1 (queue active)
Jan 9 02:45:42 ns1 postfix/smtp[13796]: CA8239B010E: host mx1.optonline.net[167.206.4.77] said: 450 4.2.1 Your host 146.145.195.66 has no DNS record . If you are using a firewall please configure DNS and try again authoritative host not found (in reply to MAIL FROM command)

Found some way to troubleshoot postfix from http://www.postfix-book.com/debugging.html and tried

telnet relay-test.mail-abuse.org

but this gives relay access denied error message. Does any of this relate to the issue that I have with outlook?

[root@ns1 web1]# telnet relay-test.mail-abuse.org
Trying 168.61.4.13...

Is 146.145.195.66 your Fedora server's IP address?

 

Yes.

I get a different error when ussing Thunderbird client.
Jan 9 13:52:22 ns1 postfix/smtpd[20167]: connect from unknown[146.145.195.65]

Jan 9 13:52:30 ns1 ipop3d[21426]: Command stream end of file while reading line user=??? host=[146.145.195.65]

Thanks for all your efforts to help me.

I tried telnet to the server from a remote machine on port 25 and it cannot connect.

telnet incnetworks.com 25
gives me :
220 *************************************

Also, the maillog displays:
Jan 9 14:17:38 ns1 postfix/smtpd[13743]: connect from unknown[146.145.195.65]

I captured the incoming packets on the server:

146.145.195.65 - is the network from which I am trying to connect
172.16.2.1 - is the private IP of the FC4 server
146.145.64.2 - is the DNS server of our ISP

Thanks,
Piyo

 

I wasn't very clear in my earlier posts. I am running the ISPConfig on a private IP address. The public IP address from our ISP is directly mapped to the private IP. Right noe there is no firewall on the public IP so all the traffic will be forwarded to the ISPConfig server.
Public IP - 146.145.195.66
Private IP - 172.16.2.1

I think my issue can be solved by doing split DNS. I would appreciate any comments.

Thanks
Piyo

 

The problem might be that 146.145.195.66 does not have a reverse DNS (PTR) record.
However, this isn't related to your Outlook/Thunderbird problem...

 

Thanks, Falko. I am palnning to setup the server on a Public IP and this may solve the problem. As I understand from one of your posts on another thread, ISPConfig is meant to work with machines connected directly on the internet. I tried doing the split DNS and was stuck with few things.

Thanks,
Piyo

 

Yes, that's right.

 

thanks falko. i have everything working now after installing ISPconfig on a public IP address. thanks again for all the hardwork.
