    I have a Ubuntu 10.04 server with ispconfig installed with the perfect server guide.
    I'm having problems with a very high load average thats makes me reboot the system.
    A ps aux show me a lot of processes like this:
    postfix  13499  0.0  0.0  12444  1824 ?        S    14:00   0:00 smtpd -n smtp -t inet -u -c -o stress=
    postfix  15852  0.0  0.1  11940  2408 ?        S    14:18   0:00 smtpd -n -t inet -u -c -o content_filter= -o local_recipient_maps= -o relay_recipient_maps= -o smtpd_restriction_classes= -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks= -o strict_rfc821_envelopes=yes -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks -o smtpd_bind_address=
    Is this normal or is it a spam attack?
    Thanks in advance

    The processes do not indicate if thats a spam attack or not as processes for normal mail have the same parameters then processes that deliver a spam mail. Take a look at your mail.log and mailqueue if you like to know if the high load is related to a spam attack.
