Setup mailaccount

[mike]

Hi,

I have followed the SuSE 9.2 server "The Perfect Setup".

Now how do I create a mailaccount using courier imap?

First you have to tell Postfix to deliver emails to a user's Maildir:

postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

Then you have to create a system user and a password:

useradd -d /home/sample_user -g users sample_user
passwd sample_user

Then run

postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable'
postconf -e 'mydestination = /etc/postfix/local-host-names'

/etc/postfix/local-host-names should contain all domains that you want to accept emails for, e.g.:

localhost
your.server.name
localhost.your.server.name
example.com
yourdomain.com

/etc/postfix/virtusertable looks like this:

info@yourdomain.com  sample_user
thomas@example.com  sample_user
webmaster@yourdomain.com  sample_user

Emails for info@yourdomain.com, thomas@example.com and webmaster@yourdomain.com will now arrive in the mailbox of sample_user.

Everytime you change /etc/postfix/virtusertable you have to run the following command:

postmap /etc/postfix/virtusertable

Now restart Postfix:

/etc/init.d/postfix restart

and you're done!

Thanks Falko! It is working...

What's the difference between using /etc/postfix/virtusertable and /etc/aliases?

[falko]

/etc/aliases maps the mails for existing system users to another system user. virtusertable defines the email addresses that belong to a system user.

I have my /etc/aliases file mapping non-existing system users to a system user and it works fine, so I don't quite understand?

etc/postfix/local-host-names

the above file contains no info and when I try and open it says new file. So do I create files that do not exist. as I ran the command prior to the above. I used webmin to add users. Again I am using just local or system users no virtual users

Thanks

Yes, you must create that file.

Ok, I reread this and it makes sense... too many late night linux installs.

info@yourdomain.com sample_user
thomas@example.com sample_user
webmaster@yourdomain.com sample_user

Since my users are accepting mail for only one domain-WOuld it look like this
thomas@example.com jthomas
thad@example.com sthad
thompson@example.com jthompson

So what I am saying is if I have only one domain and the user is accepting mail for that single domain, does each user need to be put in like above?

Thanks
