<br>&gt;
<br>&gt; today I&#39;ve noticed a problem with the ossec-maild process.
<br>&gt; The ossec.log keeps saying
<br>&gt;
<br>&gt; ossec-maild(1223): ERROR: Error Sending email to 127.0.0.1 (smtp server)
<br>&gt;
<br>&gt; Of course I started troubleshooting the problem and tried to send several
<br>&gt; test-emails from the ossec master.
<br>&gt; I&#39;m using ssmtp through my google-mail account by the way.
<br>&gt; All test mails that I sent arrived immediately, so sending mails through my
<br>&gt; MTA seems to work as usual.
<br>&gt;
<br>&gt; Then I checked the mail log /var/log/maillog-20151220
<br>&gt; which to my surprise has the latest mail entry from yesterday 19:30
<br>&gt; Dec 19 19:30:03 tron sSMTP[3943]: Sent mail for <a \
rel="nofollow">b...@bla.org</a> (221 2.0.0 <br>&gt; closing connection \
u126sm11888435wme.3 - gsmtp) uid=48 username=apache <br>&gt; outbytes=1898
<br>&gt;
<br>&gt; changed the email address to <a rel="nofollow">b...@bla.org</a> for \
demonstration purposes... <br>&gt;
<br>&gt;
<br>&gt; at least the two test emails that I just send should appear in this log,
<br>&gt; right?
<br>&gt;
<br>&gt; I know that the root cause to this problem is NOT an ossec problem....but
<br>&gt; maybe you have an idea what the problem might be?
<br>&gt; I&#39;ve checked the quota settings in my gmail account, (so far only 10%
<br>&gt; used...)
<br>&gt; I&#39;ve also checked the disk space on my ossec master, still 21GB left on \
/ <br>&gt; (where also /var is mounted)
<br>&gt;
<br>&gt; so I doubt it&#39;s a quota or diskspace problem.
<br>&gt; i&#39;ve also restarted (stopped and started) ossec, to see if any zombie
<br>&gt; processes still allocated the filesystem, and it therefore showed that
<br>&gt; plenty of diskspace was available.
<br>&gt; but even after the restart of ossec it still shows that it has plenty of
<br>&gt; diskspace available.
<br>&gt;
<br>&gt; any other ideas how I could troubleshoot this problem?
<br>&gt;
<br>
<br>Make sure ssmtp is still listening on 127.0.0.1.
<br>Use tcpdump or something similar to sniff the traffic between
<br>ossec-maild and ssmtp.
<br>Turn on debugging on ssmtp?
<br>
<br>&gt; thanks,
<br>&gt; theresa
