Wrong server host name in mail header

[sybux]

Hi all,

I'm running zimbra from a quite bit long but I hasn't realise that I was issuing a configuration problem.

Time to times, some mail server reject my email. After looking around, I've seend that the mail sender server (mine) is in fact localhost and not my FQDN mail server.

How and where can I correct this ?

By the way, I'm running 2 domains on my Zimbra config.

Thx in advance.

Welcome to the forums

Are you able to post the headers from one of the rejected messages ?

here is an example of header generated by my mail server :

Are you sending directly to the internet ? perhaps you would post the following from your Zimbra server

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes

[sybux]

/etc/hosts :

127.0.0.1       localhost.localdomain localhost
192.168.23.11   mail.lambda.com mail

# The following lines are desirable for IPv6 capable hosts
#::1     ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters
#ff02::3 ip6-allhosts

/etc/resolv.conf :

nameserver 212.27.40.241
nameserver 212.27.40.240

host `hostname` : Host mail not found: 3(NXDOMAIN)

is it really hostname or something else ?

[sybux]

nobody to help me ?

[Bill Brock]

Who is proxad.net. They have to be in the mix somewhere.

[sybux]

My own Zimbra server sits on a free.fr IP address and I don#t have any problem sending mail. Are yoy relaying through the proxad mail servers? You have the following entry in your DNS records:

mail.lambda.com.         4144    IN      A       xxx.yyy.zzz.www

Does that IP address point to the LAN IP of your Zimbra server which I assume, is 192.168.23.11?

No, it's pointing on my public IP.

The problem is not sending email, it's sending well header formated email.
