What Hostname to keep for Ideal Mail Delivery

[mehargags]

Hi Imperio & other Seniors...

I'm going on a bit of confusion...
Can you suggest in general case, what should we keep as out VPS Server's Hostname for a mulch-domain hosting ?

for eg: I have my domain name as mehargags.com.
Should I have my VPS hostname as mehargags.com or something like srv.mehargags.com ?

I'm asking this in the context of Email Delivery and other Authenticity checks that are done for IP's and Mailhosts.

I have one of my server's hostname set = domain.com but then I find that server isn't able to route mail to its own domain name with : exim -bt [email protected].

Or is there a better way to configure all this ?

Pls suggest

Hostname must be Fully Qualified Domain Name (FQDN), such as hostname.expample.com
Personally i use host.domain.com

[mehargags]

Sim,
I do understand hostname should be a resolvable FQDN, however that was not my question.

My Question is: Is it OK to have a domain.tld as your VPS's Hostname ? or will it have any consequences or other problems ?

I also want to know what generally people tend to do when they make their Servers/ VPS

I can't imagine you running into any issues not using a subdomain as a hostname though I haven't used it myself.

My convention is server***.domain.tld.

*** denotes the server number, eg. 013.

you don't seem to have your hostname setup properly.
pls check /etc/hostname and make proper entries.
Need to check your Exim configs too

thanks Mehargags, I have Hosts file not hostname (Centos 5.5) :
[root@srv1 etc]#
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

127.0.0.1 localhost.localdomain localhost

Make it like this:

127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
SERVER's_IP hostname.domain.com hostname

Replace SERVER's_IP with ip assigned to the server and hostname.domain.com with your current domain/ hostname.
