    How to Configre SquirrelMail in RedHat

    First you need to configure all service to start at boot time on redhat by this command.
    Code:
    chkconfig sendmail on 
    chkconfig httpd  on 
    chkconfig dovecot on
    Then need to configure /etc/hosts file. In my set-up /etc/hosts file will look like this:
    1
    Code:
    92.168.0.14    linuxbox10   www.asdfg.com
    Check that and reply.

    I will tell you the outgoing Mail Server Configuration by Sendmail. You need to open /etc/mail/sendmail.mc file and change the following two lines.
    From:
    DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
    FEATURE(`accept_unresolvable_domains')dnl
    To:
    dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
    dnl FEATURE(`accept_unresolvable_domains')dnl
    Then save and exit the file. Actually the first line here enables sendmail to be given incoming emails on all installed the NICs. or else mail server would only be able to receive mails from it. Best of luck.

    You need to allow RELAY for trusts IP addresses that you desire to permit sending emails using this mail server. You need to open /etc/mail/access in this file detail all those addresses that will be sending emails through this mail server. At the end of this file add the following line:
    Code:
    192.168.0 RELAY
    Save and exit and change this text database into DB format by this command.
    Code:
    makemap hash access.db < access 
    If you need more information. Please reply.

    How to Configre SquirrelMail in RedHat

    Command sendmail so as to it will be substitute as a primary mail server for "asdfg.com" domain. You can do this by adding domain name in /etc/mail/local-host-names. If this server is substitute as a mail server for more than one domains then put in names of all of the domains in this file on separate line. Open the /etc/mail/local-host-names and add "asdfg.com" at the end of this file. Also make sure that a mail server can perform as a main mail server for more than one domains at the same time and in addition to can act as a main and secondary mail server for extra than one domain at the same time. Check that and reply.

    At last you need to create mail users as well. Now create mail only users by this command :
    Code:
    useradd -s /usr/sbin/smrsh mailuser1 
    useradd -s /usr/s2n/smrsh mailuser1
    Also you nedd to set their passwords by this command.
    Code:
    passwd mailuser1 
    passwd mailuser2
    Finally restart the sendmail service by
    Code:
    service sendmail restart
