    hi all :) great forums !

    anyway, i've got a VPS with a few accounts on it. I recently brought over a site from another less reliable and less secured server.

    All is fine, but this site flags up warning on CSF as follows, normally two or three a day..

    Suspicious process running under user security
    Command Line (often faked in exploits):
    spamd child
      Excessive resource usage: security (1405)
    Account:      security
    Resource:     Process Time
    Exceeded:     12643 > 1800 (seconds)
    Executable:   /usr/bin/perl
    Command Line: spamd child
    'security' is obviously the name of the account.

    In the mail rejection logs, i'm also seeing "Rejected MAIL: "REJECTED - Bad HELO - Host impersonating (security account domain)" relating to that account. I'm not seeing this for any other account on the server.

    My hosts say this is nothing to worry about, and 'perhaps this account see's more spam than others'. I'm not so sure. I know the alertis coming from the spamassassin perl script triggering CSF, but why only this account and none of the other 25 odd? They all receive spam to some degree.

    Is it possible the security account is being compromised in some way?

    You might try the CSF forums where there are many topics about these email alerts.
