Hi all,

How can we add user mailbox?

Thanks in advance

i think its not possibe.
You must have to create user account, but you may set user's login shell to /bin/false or /bin/noshell so that user just can only access his/her mailbox but cant login on the system.

following command will create user 'james' and set user's shell to /bin/false so that james cant login on the system(but can access email using MUA eg thunderbird/Evolution/kmail or MS Outlook etc)

#useradd james -s /bin/false

You don't need an account to receive mail for a pretend user.

You can use an alias to deliver mail to a mailbox, even without an account. You won't be able to POP it off, only access it locally however.

As for sending, unless you've turned on authentication, then you can send as any user you want.

Adding a line to '/etc/aliases' like:

fakeuser: /var/spool/mail/fakeuser

Then running 'newaliases' will accept mail for 'fakeuser@yourdomain'.

If you use 'sendmail' directly to send a message, then the '-f ' flag is your friend.

If you are sending via SMTP, then make sure the client is set up to use the right sending address (which it then puts in the 'MAIL FROM: ' command).

If you want to use 'mail' (or 'mailx' or 'mutt'), well I'm not even sure you can do that.

Thanks Stuart again,

Now I want to setup MUA with fakeuser account on another machine other then mail server. I did it and start dovecot services on mail server also.

But when fakeuser account fatch the mail from Mail server, It is asking for fakeuser account password.

How can i set fakeuser password?

umm..

Using this method, you can't set a password for it to be collected. If you want to collect it, then set up a username/password pair as normal.

Hi Manoj,

Just create normal account, disable any logins (ssh, ftp,telnet) for that account and you will have mail only user.
