    I actually know nothing about ClarkConnect. from their site it appears to be using postfix for the smtp. If it is postfix then your log file should be something like /var/log/mail.log (or mailinfo)

    ssh to the machine and and run this
    #tail -f /var/log/

    this will show the transactions to your mail log in real time. CTRL-C to exit

    then on a client telnet to the machine, telnet machinename smtp_port

    you should get an smtp greeting. follow this Telnet - SMTP Commands (sending mail using telnet) to send a test email. use valid from and to and ones you can check. report back if you notice any strange messages in this telnet session. And then report your transaction for this email from your log file, like if its deferred or not.

    if you need to narrow the tail command down do this
    #tail -f /var/log/mail.log |grep

    this should only show you transactions for

    if clarkconnect doesn't use postfix then sorry for wasting your time.

    If your sites/server is using php for uploading check the file php.ini
    And the File Uploads option appropriatly.

    who |grep -i blonde |
    date; cd~; unzip; touch;
    strip; finger; mount; gasp;
    yes; uptime; umount;
