Re: connection timed out, sending to external adress like gmail or other

Looks like a DNS issue. Do you have correct DNS server(s) in /etc/resolv.conf?

Re: connection timed out, sending to external adress like gmail or other

in resolv.conf i have:
nameserver 127.0.0.1

(before isntalling i tried to set up bind9, but..... my exerience is not enoungh do do it correctly)

Re: connection timed out, sending to external adress like gmail or other

Then use a working DNS server please. For example, Google DNS servers:

nameserver 8.8.8.8
nameserver 8.8.4.4

Re: connection timed out, sending to external adress like gmail or other

i added my isp-s nameserver and these google nameserver to resolvcon then resolvconf -u , service postfix restart, nothing changed

Re: connection timed out, sending to external adress like gmail or other
