Topic: Can't send to or receive from external domain.

Hello,

I recently installed iredmail on a CentOS 5.5 VM and I can only send mail to internal users.
I've tested the connection from outside the LAN and it has the same behavior.

Here are some logs:
...

I've already checked the destination domains with host or dig and they resolve.

I googled around and found nothing. Any help would be great.

Thanks in advance.

Re: Can't send to or receive from external domain.

You can try to query virtual domains & users from LDAP with 'postmap' command. e.g.

# postmap -q 'domain.ltd' ldap:/etc/postfix/ldap_virtual_mailbox_domains.cf

Re: Can't send to or receive from external domain.

I did a check of my virtual domain from http://mydomain/ldap and it looks ok. It was created with the script included in the iredmail/ldap integration (the script to create users).

Is it possible that this is the default behavior?
I mean that only users from mydomain can email each other and not from an external domain or to an external domain.

Re: Can't send to or receive from external domain.

by default , iRedMail can reveive and send any domain.

Re: Can't send to or receive from external domain.

Well I guess I did something wrong when I installed it, so at this early point a clean install wouldn't harm.

Thanks again and I'll let you know if this corrects my issue.

Re: Can't send to or receive from external domain.

I belive I solved it.

Searching on how does Postfix lookups names I found that in my case, with a clean iRedOS install, theres is another file 'resolv.conf' in '/var/spool/postfix/etc/' besides the one in '/etc/', so Postfix must be running chrooted (correct me if I'm wrong).

The two files were different so I only needed to copy the one in '/etc/' (because that one was working with host and dig)to '/var/spool...' and that corrected my problem.

I hope this helps to deal with similar issues.

Re: Can't send to or receive from external domain.

No, thanks to you for your excellent work.

I'd like to add something: I needed to disable TLS in '/etc/openvpn/auth/ldap.conf' in order to make OpenVPN work with your integration howto. And because I'm using x64 I needed to change the location of the plugin 'openvpn-auth-ldap.so' to:

/usr/lib64/openvpn/plugin/lib/openvpn-auth-ldap.so

in the file '/etc/openvpn/server.conf'.

Re: Can't send to or receive from external domain.

I'm experiencing a similar problem when trying to install the iRedOS on my XEN server.

Similar to what's reported above, the installation process is unable to setup my domain name (FQDN) properly. All configurations are "localhost.localdomain" and I answered the CentOS install prompt for FQDN appropriately.

Looks like it's something related to the virtual environment.

Please help if you can.

Regards,

Re: Can't send to or receive from external domain.

Just tried again a fresh new install of iRedOS under my XEN server.

I think the initial configuration script (iRedMail actually) isn't going to the end but I do receive a "successful installation of CentOS" screen in the end.

This virtual machine has enough free space (10GB) during install and 512MB of system memory allocated.

I'm trying to install the 64-bit version of iRedOS.

Any suggestions?

Regards,

iRedMail uses output of command "hostname -f" to get FQDN, you should make sure it's correct before installing. It's mentioned in iRedMail installation guide.

Re: Can't send to or receive from external domain.

Dear friend,

I noticed that trying to create a new VM machine under XEN using the iRedOS CD won't create a paravirtualized machine, which isn't the ideal scenario. The iRedOS CD, understandably so, doesn't include the CentOS "XEN-ready" kernel. A paravirtualized kernel would output:

"Kernel 2.6.18-128.el5xen on an x86_64"

And that's what I did. Started by selecting the CentOS V.5.3 template included with Xen Server V.5.6 and selected a very bare minimal number of CentOS packages. Then followed the iRedMail script install guide and it worked great!

Finally, issued a "yum update" command and things look pretty ok now!

Regards,

16

Re: Can't send to or receive from external domain.

Thanks for your feedback, i will try to ship Xen kernel in next release. smile
