    I set up an Ubuntu Jaunty Jackalope (Ubuntu 9.04) vps server with ISPconfig 2 following this tutorial http://www.howtoforge.com/perfect-server-ubuntu-9.04-ispconfig-2

    All seems to work quite allright but now I run into a problem regarding postfix and smtp.

    When I try to send an email I get:

    mail.log
    Code:
    postfix/smtpd[6517]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
    postfix/smtpd[6517]: warning: host250-228-dynamic.17-87-r.retail.telecomitalia.it[87.17.228.250]: SASL LOGIN authentication failed: generic failure
    postfix/smtpd[6517]: disconnect from host250-228-dynamic.17-87-r.retail.telecomitalia.it[87.17.228.250]
    
    Could anyone help me?

    Please try this:
    Code:
    adduser postfix sasl
    /etc/init.d/postfix restart
    /etc/init.d/saslauthd start

    /etc/postfix/sasl/smtpd.conf
    Code:
    pwcheck_method: saslauthd
    mech_list: plain login
    
    /etc/default/saslauthd

    Code:
    START=yes
    
    DESC="SASL Authentication Daemon"
    
    NAME="saslauthd"
    
    MECHANISMS="pam"
    
    MECH_OPTIONS=""

    What's the output of
    Code:
    ls -la /var/spool/postfix/var/run/saslauthd/
    ?

    What virtualization technique do you use (OpenVZ/Virtuozzo, Xen, KVM, VMware, etc.)?

    Looks ok. Are you absolutely sure that the postfix user is a member of the sasl group? What's the output of
    Code:
    grep sasl /etc/group
    ?
