[SOLVED] Configure Postfix & Dovecot to NOT use system users.

Looks like you didn't create the vmail user with uid 5000.

yeah "vmail" user has this id in postfix to be setup, i was trying to recall it.. thanks for reminding.

Hey,

I ran the command as you stated in your previous reply but it did not show anything as you can see below:

Quote:

root@server.aevtech.com [~]: awk -v val=5000 -F ":" '$3==val{print $1}' /etc/passwd
root@server.aevtech.com [~]:

If this user name is not on the server, where did it find the information for this user which is in the error?

Presumably because you have set your postfix virtual transport to use uid=5000:gid=5000

SAbhi · 08-26-2013, 02:13 AM

refering your comment "you followed what is sent"

from here it would have came::

Code:

sudo groupadd -g 5000 vmail

To create a virtual mailbox owner:

sudo useradd -m -u 5000 -g 5000 -s /bin/bash vmail   ##### YOU forgot to execute this

Edit main.cf

sudo vi /etc/postfix/main.cf

Set up Postfix to use virtual mailboxes

Add the following code segment to main.cf

virtual_mailbox_domains = /etc/postfix/vhosts
virtual_mailbox_base = /home/vmail
virtual_mailbox_maps = hash:/etc/postfix/vmaps
virtual_minimum_uid = 1000
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000

Hello,

I have tried to run the missing command and got the following:

root@server.aevtech.com [~]: sudo useradd -m -u 5000 -g 5000 -s /bin/bash vmail
useradd: group '5000' does not exist
root@server.aevtech.com [~]: groupadd 5000
groupadd: group '5000' already exists

I checked everything else and that was done and good to go. But, how come it is telling me the group is not there in one error and it tells me it is in another?

useradd: group '5000' does not exist
root@server.aevtech.com [~]: groupadd 5000
groupadd: group '5000' already exists

The above is wrong execution.

Now try to understand what the command is doing:

Code:

sudo groupadd -g 5000 vmail          # add a group with gid 5000 and name vmail

sudo useradd -m -u 5000 -g 5000 -s /bin/bash vmail             #Add a user with uid 5000 gid 5000, a default home directory and name vmail.

See above and compare what mistake you were doing since the start on this procedure.
Go ahead delete the existing group you created incorrectly and create again with above commands.

Hello,

YES!!!!!! It is working!!!!!

I MY SELF messed up before but you helped me see the errors I have done and I thank you guys so much for the help!!!!

I sent a test e-mail to support@aevtech.com and it went through with no errors or anything and created the directories and no email with no errors.

I used roundcube to log in. I want to log in with support@aevtech.com and a password for it.

How to do I assign it a password so I can log into round cube with the email address (full email address) and its password?

SAbhi · 08-27-2013, 10:24 PM

well thats great....

For now i dont know much about roundcube, so its better to mark this thread as SOLVED and open a new thread to figure out how to assign password to these email addresses and access them in Roundcube.. someone should have info on that.
meanwhile i will try configuring roundcube on my test machine and will do some R&D on your requirement.

Dovecot is what your webmail will be logging into, so see the documentation at dovecot.org on the various auth methods available.

SAbhi · 08-27-2013, 10:32 PM

Yeah i thought you have already set it up for dovecot as the link i shared has the info of setting the users and password using dovecot too and the same can be used in Roundcube ...after what i have searched so far about roundcube.

So follow the documentation again for dovecot and you are all set to go to use it for roundcube.
@descendant_command: Thanks for the hint
