Configure LAN mail account in thunderbird

Hello everyone,
I have a problem regarding mail server and client.
Postfix and Dovecot are installed on Linux server. hostname of the Linux server is 'sys.local'. Users have been created on the server. If I send a mail from Linux server's terminal using one of the user's account(james), it is sent as james@sys.local

I want to configure this user account in thunderbird on my system(of same LAN).
I am not able to configure it. I have defined server's IP with hostname in my /etc/hosts file. 143, 110 & 25 all necessary ports are opened and defined in firewall.

If I configure same account in server's thunderbird, it is configured correctly but not on other systems of same LAN.

I am using ubuntu 12.04.

Please help.

Thanks You

--Kind Regards

You shouldn't use .local for tld, it is reserved for mDNS. Short description:
"...the DNS top-level domain ".local." is a special domain with special semantics, namely that any fully-qualified name ending in ".local." is link-local, and names within this domain are meaningful only on the link where they originate. This is analogous to IPv4 addresses in the 169.254/16 prefix..."
Some suggest you just remve the mDNS in hosts line in /etc/nsswitch.conf, but I strongly advice aganst hacks like that - you'll have to do it on every *nix client, and it might cause problems later on, at a time when you completely forgot you changed that file.

Simple solution: use other domain name.

Thanks for your reply.
I do not have domain name. I have 20-25 systems and a Linux server in a LAN. I want to implement mail server to use in LAN. I do not want to receive mails from outside LAN because I know I can't. I do not have domain name.

Postfix and Dovecot has been installed on Linux server. 20-25 Linux users has been created on the server. I want to send and receive mails between these 20-25 systems of LAN. Each system has thunderbird and we want to configure server's user's account on different systems.

What value should we give of 'myhostname' and 'mydomain' in of postfix?
Any other specific setting in which is necessary to send mails locally?
Do we need to change any value in dovecot.conf?
When I try to configure mail account in thunderbird, it is not able to find the mail account, but it finds if I configure same mail account in server's thunderbird (it is not allowed but I confirmed somehow. )

Thanks again and Please help.
