ISPconfig 3 - Mailserver Warning
 
Hi,

Anybody that can tell me what these 2 warnings from the mail-log mean - Can't receive mail by the way:

Relay access denied
warning: dict_nis_init: NIS domain name not set - NIS lookups disabled

It's the "relay" warning which is the reason I can't receive the mails, I guess..

In the ISPconfig CP "System > Server Config > Mail" there is an "error" when I leave the site:

ERROR
Please specify valid RBL hostnames.


Added: zen.spamhaus.org - Error message in ISPconfig CP went away. but still not receiving any mail...

Have been reading several sites, tutotials and manuals - but still I am very much i doubt. Is it in the shell there need to be changes or is it in the ISPconfig3 CP? Heres some of the sites I found regarding this problem:

1. ISPconfig3 Manual: page 189 "4.7.6.4 Relay Recipients"
2. ISPconfig3 Manual: page 225 "Server > Server Config > Mail" Relay Host/Relay User
3. http://beginlinux.com/server_trainin...-server-set-up "4. Configure Relays"
4. http://www.howtoforge.com/forums/showthread.php?t=53319 Where the mydestination line in your main.cf was the problem
5. http://docs.oracle.com/cd/E19563-01/...avb/index.html "18.7.4 To Use DNS Lookups Including RBL Checking for SMTP Relay Blocking"

Could nr "5" be a solution to the second error message - and then maybe both error messages are related?:

warning: dict_nis_init: NIS domain name not set - NIS lookups disabled

It's a warning, not an error. You eliminate it by removing
NIS lookups.

First, find out what setting is using NIS:

$ postconf | grep nis:

This outputs something like

alias_maps = hash:/etc/aliases nis:mail.aliases
or
alias_maps = hash:/etc/mail/aliases nis:mail.aliases

Then, disable NIS lookups (as root):

# postconf -e alias_maps=hash:/etc/aliases
or
# postconf -e alias_maps=hash:/etc/mail/aliases

The exact command depends on "postconf | grep nis:" output.


First thing you should do is to check if SMTP is up and running.
On mail server you can check this with this command...

Quote:

netstat -tapn
Can you see SMTP? (Usually on port 25.)
If that is up then you are most likely dealing with a DNS problem (NIS lookups seem to indicate that anyway.)

Hi Sam,

Thanks for your reply.
I will try that command right now to see what I can learn from that.

Thanks for the fix above. :)
