1 to four mail boxes (True or False)?

I just want to know if it is really possible:

My network provider give me one mail box and allow me to define 3 aliases to this mail box. For instance, the email account is info@mydomain.com, I can have three aliases (staff1@mydomain.com, staff2@mydomain.com, staff3@mydomain.com) to the same mail box. As a result, when I login to the smtp.mydomain.com with "info", I can get all message from these four email addresses.

Question: Can I use fetchmail and sendmail to download all messages to my local mail system, and let four users to get their messages from this mail box individually? User should login local mail server as info, staff1, staff2, staff3.

(Is it called masquerading from the sendmail handbook?)

I would be very happy to give more point for someone give me more tips to do this. Thank you very much.

Yeah but you still haven't specified the localdomains line have you?
Also as for point 4 of no relaying you can solve that using the relay-domains file to allow your local network or your domain to relay through your mail server.
I will give you an example of how what I said works if it applies to you then take it up
I have a client with his domain as client.domain.name his mx records point to my.server.name and I have an account on my box called client into which I direct all this mail.
So he gives people e-mail accounts at client.domain.name say user1@client.domain.name user2@client.domain.name etc and all this goes to that one mail box called client on my box then he he has a .fetchmailrc file which he runs as root that reads
poll myserver protocol pop3 nodns
localdomains client.domain.name host.client.domain.name
user username pass passwd to
root
*
here
and his sendmail.cf has a line specifying that client.domain.name is a local domain i.e
Cwclient.domain.name
Cwlocalhost
when he runs fetchmail -va the mail is delivered to user1 user2 etc's mail boxes also there should be an entry in etc/hosts for client.domain.name.If this is the kind of setup you have then it should work if you set it up this way.

if your mail server is called mydomain.com then you just simply have to create those accounts as they are and then when you run fetchmail sendmail will send this mail to the individual mail boxes.
If not then define a Cw in your sendmail.cf file defining mydomain.com as a a domain local to your host.
then your .fetchmailrc would look like this
poll isp.com protocol pop3 nodns
localdomains mydomain.com
user (account) pass (passwd) to
root
*
here
I hope this is what you wanted

If I remember correctly from when I was doing this (many moons ago - run my own mail servers these days), you can indeed do this with fetchmail/sendmail.

In your /etc/aliases file, you will need to add some lines like :

info@mydomain.com: info
staff1@mydomain.com: staff1
staff2@mydomain.com: staff2
staff3@mydomain.com: staff3

Save the file, and execute the "newaliases" command.

Create the user accounts for info, staff1, staff2, and staff3 - these are what your staff will log into to collect their mail from your local server.

Have fetchmail poll the POP3 server at your ISP. As the messages come in, and are passed to sendmail, those messages addressed to the staffx@ addresses should be moved to the correct mail folders during the processing.

Like I say, it's been a little while since I did this, but I'm 99% sure that's all I did.

Thanks a lot.

My local mail server name is now change to mydomain.com and aliases are added, send & receive messages locally are okay but all remote messages by fetchmail are send to root's mailbox.
