Partly Unrouteable address when sending

[user_chris]

System: Ubuntu 14.04.2 LTS / Vesta 0.9.8.14

Have already tried but I get in some domains returns the error or the mail.
My guess is the hostname

etc/hosts

Code: Select all

127.0.0.1     localhost
127.0.1.1     srv1.domain.tld srv1

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

or additionally

Code: Select all

my.server.ip.xxx     srv1.domain.tld srv1

Test

Code: Select all

root@srv1:~# hostname
srv1.domain.tld
root@srv1:~# hostname -i
127.0.1.1

Must The entry remain?

Code: Select all

127.0.1.1     srv1.domain.tld srv1

And to add?

Code: Select all

my.server.ip.xxx     srv1.domain.tld srv1

Thanks!
