[SOLVED] sending/receiving mails confused

[hercules]

Hello all,
iam new in Zimbra mailserver and have some little problems with sending or receiving mails.

Here are the main data.
My domain name (fqdn): mailserver.sinsheim-wetter.de

The hostname for the simbra server is: mailserver.sinsheim-wetter.de
I have a reverse enrty thats works correct.

My mail-domain is: sinsheim-wetter.de.Thats also the defaultdomain within Simbra and for using e-mails.

ZMcontrol shows no errors ans all is running nice...at least it seems so, because i have a strange problem.

In the MTA Seetings the given domainname is (webmail MTA hostname): sinsheim-wetter.de
With this entry i can receive mails without problems, but sended mailsl doesnt work. Webmail shows " Your mail was send", but they never reach the Receipents.

When i change the MTA hostname to mailserver.sinsheim-wetter.de , i can send mails, but now i can´t receive mails. I have tried all possible solutions, but i cant understand whats wrong here.

When i start a simple mailserver like Mercury, all works fine and without any problems.

Any ideas wehre i can search for a solution?

Regards

Thomas

Welcome to the forums.

Are you behind a router (i.e. does you server have a private IP)? If you are you'll need a Split DNS setup. You should also check your hosts file. To check your set-up run the following on your Zimbra server:

host `hostname`   <-- backticks not single quotes
dig sinsheim-wetter.de mx
dig sinsheim-wetter.de any

hello,

first thanks for the very quick answer:-) Ic have a router..here you are right.

The results of the commands are below. May you can explore some errors?

Again..thx for the help:-)

You will need to run a local DNS server so that Zimbra (actually Postfix) can resolve the server LAN IP via DNS, follow the Split DNS instructions in the link I posted above. You also didn't run the

host `hostname`

command to check your host file.

Ho phoenix,

yes i tried the documentation behind the link above, but it wont work right now, because it is
for a RED HEAD LINUX, but i use SUSE 10.2.

I could install bind, but there was many errors during ste setup. I dont undersatnd where i have to insert which hostname oder IP into the configs. Also its not clear that the nemaed.conf entries are additional to the exisiting named.conf, or stand alone, so that i hace to overwrite the exisiting named.conf.

The results of the host command is here:

mailserver:~ # host mailserver.sinsheim-wetter.de
mailserver.sinsheim-wetter.de has address 194.231.187.137
mailserver.sinsheim-wetter.de mail is handled by 100 sinsheim-wetter.de.


Its heavy..but not impossible;-)
