Hi all,

For installing a mail server (postfix) for an
organisation, is it necessary to have one Valid IP? or
not an issue.

please explain?


You need to have a permanent live IP for your organization if you plan to keep 
a mail server (also generally known as mailgate) with yourself. In this case 
your mail server will directly send and receive all the mails for your 
organization to external domains.

Alternatively you can render services from mail service providers like Yahoo or 
Rediff. They receive & send all the mails for your organization. In this case 
your server will SMTP/POP  mails of your organization to/from the Yahoo/Rediff 
server. Here you dont require a permanent live IP address. Also a plus point 
would be you can avail many advanced features like spam protection and 
Antivirus check already available with them.
