</div></div>Unless you installed them someway that didn't honor the dependencies, that should be plenty. Any error messages in your logs?</blockquote><div><br>nada. the default container isn't making any logs either, but it did send the mail<br>
</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">WHY can't it send mail?</blockquote><div><br>sure wish i knew! /bin/mail of course gives no error.<br>
</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Look at the CentOS/RHEL deployment guide and you'll see that by default they only accept inbound connections from 127.0.0.1 (<a href="http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Deployment_Guide/s1-email-mta.html#s2-email-mta-sendmail" target="_blank">http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Deployment_Guide/s1-email-mta.html#s2-email-mta-sendmail</a>) so if you haven't changed that, you'll need to. So far as sending email goes, you should be able to send just fine.<br>
</blockquote></div><br>sending is all i want. nagios is working fine. nagios and sendmail is all i all i have or want in this container. everything installed from rhn repositories with rhel yum, no conflicts or errors.<br>
