    Am having the following error and can't seem to put my finger on it:
    postfix/master[11340]: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling
    postfix/smtp[11364]: fatal: chroot(/var/spool/postfix): Operation not permitted
    postfix/master[11340]: warning: process /usr/libexec/postfix/smtp pid 11364 exit status

    I installed Postfix, Mailscanner, Clamav, Courier on Centos 5.

    Any help will be greatly appreciated.

    Can you post your postfix configuration?

    Can you change
    Code:
    127.0.0.1:10025 inet n - - - - smtpd
    to
    Code:
    127.0.0.1:10025 inet n - n - - smtpd
    in master.cf?
    If that doesn't help, what's the output of
    Code:
    ls -la /var/spool
    ?

    Clamav not starting

    The problem was also with the amavis configuration which I changed from:
    Code:
    amavis unix - - - - 2 smtp
    
    to:
    Code:
    amavis unix n - n - 2 smtp
    
    Now clamav is refusing to start:

    clamd.conf
    Code:
    LogFile /var/log/clamav/clamd.log
    LogFileUnlock yes
    LogFileMaxSize 1M
    LogTime yes
    LogSyslog yes
    PidFile /var/run/clamav/clamd.pid
    TemporaryDirectory /tmp
    DatabaseDirectory /var/clamav
    LocalSocket /tmp/clamd.socket
    FixStaleSocket yes
    TCPSocket 3310
    TCPAddr 127.0.0.1
    MaxConnectionQueueLength 30
    StreamMaxLength 20M
    MaxThreads 10
    ReadTimeout 300
    User clamav
    AllowSupplementaryGroups yes

    ls -la /var/
    Code:

    drwxr-xr-x 25 root   root    4096 Jun  6 02:15 run
    drwxr-xr-x 18 root   root    4096 Apr 22 08:12 spool
    
    Starting Clam AntiVirus Daemon: LibClamAV Error: cli_loaddbdir(): Can't open directory /var/clamav
    ERROR: Unable to open file or directory

    I have no idea what I've done wrong, because clamav was working before I restarted.

    Any help will be appreciated... Thank you.

    Clamav not starting

    Clamav start when I invoke it directly like this:

    Code:
    # clamd start
    but fails to start when invoked liked this:

    Code:
    # service clamd start 
    thats when the error shows up.
    :(I find that very strange.
    :confused: Probably because I don't know or understand what is happening...

    :) I got it working, but am facing another problem...

    Connecting to amavis transfer refused! :mad:

    Am tired for today so I will look into it tommorrow.

    Can you restart amavisd?

    If that doesn't help: what happens if you remove all the n from the chroot column in master.cf?
