DNS issue virtualmin with email

okey, the network looks like this
wan/ISP<->router<->server (<-> webserver)
the dns client is installed on server, not on the virtual webserver.

this is the error…
May 29 20:53:19 webservern postfix/smtp[5003]: 330E3123EFB: to=, relay=none, delay=84411, delays=84391/0.06/20/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again)

thanks for reply


It looks like you’re seeing a DNS issue.

What are the contents of your /etc/resolv.conf file?


this is from the webserver (vm)
nameserver 83.255.245.***
nameserver 193.150.193.***

for the moment i dont have root access to the server to check resolv.conf… =/
witch one is important to know about?


Well, the contents of your /etc/resolv.conf file specify what DNS servers your server would be using. Since it appears that your server isn’t able to perform DNS lookups, there may be a problem with the DNS servers listed in /etc/resolv.conf.

Whenever you’re able to log in, my suggestion would be to review that file, and verify that all the nameservers listed in it are working properly.


got root access today for my server :slight_smile:

this was it…
