Re: [vps-mail] Question re syntax for hosts.allow file

Hi,

 ah tcp wrappers !

Both will work well but the first is cleaner as the second will also
catch domains starting like the ip ;)


  As a little rule of filtering ,  you should have only "allow" rules
in  it with the last a "deny all":

exemple :

ALL : localhost 127.0.0.1 : allow
pop3 pop3s pop3pw imaps imap ftp ftps : ALL : allow
smtp : all except 207.164.7.0/255.255.255.0 : allow
ALL : ALL : deny

  This is like for firewalls , the best is to close all and open what
you need. This is the most secure way of doing this IMHO.

for more info about how to use tcp wrappers on VPS :

man 5 hosts_options
man 5 hosts_access

 Hope it helps :)

best regards,
Ghislain.
