How to create virtual mail clients on app2.safemobile.com.

How to create virtual mail clients on app2.safemobile.com.

There are 3 services that have to be updated:

+ postfix

+ sasl

+ courier

1. POSTFIX

To update the postfix service, you have to:

+ 1. make sure the do 353r175d main is in the /etc/postfix/main.cf file, eg:

virtual_mailbox_domains = app2.safemobile.com airadio.com

Any new domain should be added on this line, separated by a space. If the main.cf file is changed, postfix should be restarted

# service postfix restart

+2. make sure that the user has its own mail location in:

/var/mail/vhosts/<virtual domain name>/<virtual user name>/Maildir

eg:

/var/mail/vhosts/app2.safemobile.com/dragos.anghel/Maildir

Of course, all these directories should belong to postfix.

+3. edit /etc/postfix/vmailbox and map the username to the mail directory where the mail is delivered, as in the example below:

[email protected]  app2.safemobile.com/dragos.anghel/Maildir/

After all the users have been added, issue:

# postmap /etc/postfix/vmailbox

2. SASL

Afte this, configure the sasl database

# saslpasswd2 -c -u <domain> -a smtpauth <username>
eg:
# saslpasswd2 -c -u app2.safemobile.com -a smtpauth dragos.anghel
The password is requested after entering the command.

3. COURIER

The last thing is to update the courier userdb file, used for courier authentication:
+ 1. edit the /etc/authlib/userdb
Provide the following fields, as indicated in the example below:
dragos.anghel uid=89|gid=89|home=/var/mail/vhosts/app2.safemobile.com/dragos.anghel| shell=/bin/bash|imappw |pop3pw=

Make sure that:

1. uid and gid are the same (corresponding to the postfix user).
2. after the username, there is always a tab
3. fields are separated by |

Each username must have its password generated using:

# userdbpw -md5

Once the password is generated, it should be included in the line in /etc/authlib/userdb, as follows:

dragos.anghel uid=89|gid=89|home=/var/mail/vhosts/app2.safemobile.com/dragos.anghel| shell=/bin/bash|imappw=$1$/i5p9m41$U11L38m83JuRyp298KZWw1|pop3pw=$1$/i5p9m41$U11L38m83JuRyp298KZWw1

Once this has been completed, stop the courier authdaemon:

# authdaemond stop

Make the user database

# makeuserdb

Then restart the authentication daemon

#authdaemond start

Now everything should work. The users can have different passwords for sasl and courier, which are unrelated services.
