Domain literal

[Skin]

Hello I'm trying to allow domain literals, but I have some problems:

In my /etc/exim.conf I can see:

# If you want to accept mail addressed to your host's literal IP address, for
# example, mail addressed to "[email protected][111.111.111.111]", then uncomment the
# following line, or supply the literal domain(s) as part of "local_domains"
# above.

# local_domains_include_host_literals

if I uncomment # local_domains_include_host_literals exim won't restart so I commented the line again.

Have you any suggestions?

Thanks
Alessio

Hello

You can browse to "WHM Home » Service Configuration » Exim Configuration Manager » Advanced Editor". Scroll down until you see "Add additional configuration setting" (it's just above Section: BEGINACL"). Then, select the following option from the drop-down menu:

"allow_domain_literals"

Here is it's description:

If this option is set, the RFC 2822 domain literal format is permitted in email addresses. The option is not set by default, because the domain literal format is not normally required these days, and few people know about it. It has, however, been exploited by mail abusers. Unfortunately, it seems that some DNS black list maintainers are using this format to report black listing to postmasters. If you want to accept messages addressed to your hosts by IP address, you need to set allow_domain_literals true, and also to add @[] to the list of local domains (defined in the named domain list local_domains in the default configuration). This “magic string” matches the domain literal form of all the local host’s IP addresses.

Thus, after setting the value to true and saving, you have to add the IP addresses to the /etc/localdomains file in this format:

[IP]

Thank you.

Hello,
I don't have any /etc/localdomains, should I create it?

Thanks for your reply

Yes, you should create that file if it does not exist. However, it should already exist on any server where you have installed cPanel and created accounts.

Thank you.

I'm going to create it... but it is strange: I'm using cpanel and I've some accounts on this vps.

Thanks

Are you sure you are logged in as root and spelling it correctly? EX:

[email protected] [~]# ls /etc/localdomains
/etc/localdomains

Thank you.

Hello, probably I wasn't spelling correctly: ls /etc/localdomains returns /etc/localdomains

Thanks very much
