Hi Friends,

I have got one requirement from one of my friend office, As their office requirement is, They needed one linux mail server for internal use purpose,

They don't have DNS server (Windows or Linux), and they dont wanted DNS server also because they cant register DNS (No ISP/Public IP)

They don't want external mails, just they wanted mail to access inside the office, they don't want to put their machine on internet too, just mailing will happen in local network only.

They have windows XP users/clients, just they wanted to send mail one user to another user internally / local network. Just their requirement is, they need to send / receive their mail internally by linux server. (they can use / Configure "MS Outlook" OR "Outlook Express")

How to configure as per their requirement in linux I am not getting,

Please help me on this, how to configure sendmail / Mail server without using DNS + without using 3rd party softwares.

Thanks and Regards,

I would still recommend to set up a DNS server - a private one with a made up domain name (some people use .local, some use .localdomain (I don't know if there is a standard for this))

Otherwise, what would their e-mail addresses look like? mary@192.168.100.100? That would look stupid

So, set up bind domain name server on the linux server, create a domain, point all PCs to the DNS server so that the domain could be resolved by their Outlooks and set up mail server as usual.

Hello,

It is correct that DNS server is recommended but without DNS also you can setup mailing server, you can put server IP address in SMTP and POP3 setting of outlook and start using mailing services.
