    postfix? sendmail? where does the problem come from?

    The following message appears in the SquirrelMail interface, when trying to send a message:
    Server replied: 78 Can't execute command '/usr/sbin/sendmail -i -t [email protected]'.

    ISPConfig installed on CentOS 5.4 using this perfect server guide.

    Additionally, when doing a ehlo localhost from port 25, it gives:
    ?Invalid command
    The sendmail service is stopped, and the postfix is started.

    Output of postconf -n is:
    alias_database = hash:/etc/aliases
    alias_maps = hash:/etc/aliases
    command_directory = /usr/sbin
    config_directory = /etc/postfix
    daemon_directory = /usr/libexec/postfix
    debug_peer_level = 2
    html_directory = no
    inet_interfaces = all
    mail_owner = postfix
    mailq_path = /usr/bin/mailq.postfix
    manpage_directory = /usr/share/man
    mydestination = $myhostname, localhost.$mydomain, localhost
    newaliases_path = /usr/bin/newaliases.postfix
    queue_directory = /var/spool/postfix
    readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
    sample_directory = /usr/share/doc/postfix-2.3.3/samples
    sendmail_path = /usr/sbin/sendmail.postfix
    setgid_group = postdrop
    unknown_local_recipient_reject_code = 550
    I didn't touch any of the initial definitions, and did only what the guide ordered.

    Any clue?

    Did you disable SELinux?

    That's the 1st thing I do after installing a CentOS system :)

    Thanks Falko!

    Eventually, after hitting a solid brick wall with this issue, I've moved on to a different system.

    It seems weird to me, that after going through the guide, one step after the other, there are such basic things that don't work as-is. It's too bad, since I really liked the system.

    Thank you nonetheless!

    too late for Dotan, but had a similar problem.

    Answer was to amend config.php to sendmail.postfix

    steps are :
    >cd /usr/share/squirrelmail/config
    >vi config.php

    I didn't replace syntax, but easy enough to go to line and amend setting in VI.

    maybe helps someone else if they hit this.
