Which internal mail server should i use ,any good free ware.
Just adding my query ,to ur queries...

Now presently say my mail server is mail.abc.com and i use the pop3 and smtp address as mail.abc.com

user id is [email protected].
If i configure a internal mail server ,i will need to create a mial box named Tom ,so that all the mails are stored in it.

So ,the internal mail server may have settings forthe braodband connection to initiate mail send and recieve.

As u said that create a another domain in the mail server say xyz.com and create users in it .But if tom sends mail from his pc ,does he have to parse it ...say
[email protected]<[email protected]>,since this problem may arise.

kindly let me know
