    Step by step problem

    hi falko,

    this is my problem. i fallowed the perfect Server 4.5 centos. everything works fine. i can send mail to internet and received.
    i need to setup a mailscanner and the requirements is
    sh postfix-chroot.sh enable
    and i cant find the /etc/postfix/postfix-chroot.sh, so i download the rpm postfix-2.4.3-1.rhel4.i386.rpm & installed it. now the postfix-chroot.sh appear in /etc/postfix/postfix-chroot.sh and run the chroot script


    [[email protected] tmp]# rpm -Uvh postfix-2.4.3-1.rhel4.i386.rpm
    Preparing... ########################################### [100%]
    1:postfix ########################################### [100%]
    postfix/postfix-script: warning: /var/spool/postfix/etc/passwd and /etc/passwd differ
    warning: /usr/lib/sasl2/smtpd.conf saved as /usr/lib/sasl2/smtpd.conf.rpmsave


    and telnet. no more plain login


    [[email protected] tmp]# telnet localhost 25
    Trying 127.0.0.1...
    Connected to localhost.localdomain (127.0.0.1).
    Escape character is '^]'.

    ehhlo locahost

    ehlo localhost

    250-ETRN
    250-STARTTLS
    250-ENHANCEDSTATUSCODES
    250-8BITMIME
    250 DSN


    all i notice is plain login is missing now.

    can i install the mailscanner without using the chroot ?if will, no need to update the postfix

    Please try
    Code:
    nameserver 145.253.2.75
    nameserver 193.174.32.18
    instead.
