<p>Do<br>
service MailScanner stop<br>
This is, of course, to stop both MS and your MTA. Check that all Sendmail processes have ended, with ps. Then do<br>
service MailScanner startin<br>
Which will only start the mta. Send a message to it... If it flows through, then you've got a bad Sendmail setup. If not, then do<br>
service MailScanner startout<br>
If the mail get delivered now, then your outgoing instance picks up mail from the wrong queue dir.</p>
<p>Cheers&Merry Xmas<br>

I'd look very carefully at the sendmail setup<br>
(<a href="http://www.mailscanner.info/sendmail.html" target="_blank">http://www.mailscanner.info/<u></u>sendmail.html</a>)<br>
<br>
and make sure that mail doesnot flow with MS turned off.<br>

FYI in centos 6 the default mta could be postfix if it's like red hat !<br>
So<br>
you may need to disable postfix if u want to get this going..<br>

Good point<br>
<br>
Tony - if you telnet to the server on port 25, do you get the sendmail<br>
or postfix banner?<br>

Thanks Martin and Chris for that tip, I had already discovered that and<br>
uninstalled postfix. No luck<br>
<br>
It got me thinking... what else could be delivering the mail from<br>
/var/spool/<a href="http://mqueue.in" target="_blank">mqueue.in</a>? Other than sendmail?<br>
<br>
Thanks to a lot of people with suggestions.<br>

<br>
This is what I believe is happening.<br>
Being Centos 6<br>
<br>
Postfix was installed but not running.<br>
Postfix has been uninstalled and the server restarted<br>
Telnet in and you get:<br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<br>
looking at chkconfig, this appears clean and unless some one wants<br>
something specific from it I wont report my findings.<br>
<br>
SO<br>
<br>
It would appear that emails come in on the sendmail MTA<br>
They get put in the /var/spool/<a href="http://mqueue.in" target="_blank">mqueue.in</a> directory<br>
THEN sendmail straight away picks them back up and delivers them before.<br>
MailScanner can ever get a change to process them.<br>
<br>
My reason for thinking this:<br>
<br>
I sent a number of emails from a different server.<br>
Here is sendmail getting the email as we would expect, and as emails are<br>
also received on other sendmail/MailScanner servers that are operating<br>
correctly.<br>
<br>
root 16583 0.0 0.3 10848 3952 ? D 11:34 0:00 sendmail:<br>
pBLMYFqF016583 ip-202-174-161-37.wizbiz.net.*<u></u>*nz<<a href="http://ip-202-174-161-37.wizbiz.net.nz" target="_blank">http://ip-202-174-161-37.<u></u>wizbiz.net.nz</a>><br>
[202.174.161.37]: DATA<br>
<br>
<br>
INSTANTLY though I also see this<br>
root 16585 0.0 0.3 10668 3200 ? S 11:34 0:00 sendmail:<br>
./pBLMYFqD016583 from queue<br>
<br>
sendmail picks the email back up and delivers it, MailScanner never get a<br>
change to poll the this message.<br>
<br>
How do I stop sendmail from doing this?<br>
<br>
</blockquote></blockquote>
<br>
I agree with you Martin, and am looking closely at sendmail.<br>
With MailScanner turned off no emails flow.<br>
<br>
I have even checked to make sure there is no other stray process that is running when MailScanner is running that might be activating a sendmail process to deliver emails.<br>
<br>
Turn MailScanner on emails are accepted but delivered right away.<br>
The process<br>
root 30934 0.0 0.1 10032 2012 ? Ss 11:32 0:00 sendmail: accepting connections<br>
Is accepting the connection to receive an email.<br>
A process is started to receive this email<br>
Something like:<br>
sendmail: pBMLiEI2027891 <a href="http://ip-202-xxx-xxx-37.wizbiz.net.nz" target="_blank">ip-202-xxx-xxx-37.wizbiz.net.<u></u>nz</a> [202.xxx.xxx.37]:<br>
Then a third process is started to deliver this message.<br>
<br>
It is this last step that I DO NOT what happening.<br>
<br>
Configurations between this system and other systems seem the same, except this is a different version of send mail, 8.14.4-8.el6 as apposite to 8.12.8-8.1el5_7<br>
<br>
Checked the process for accepting emails<br>
/usr/sbin/sendmail -bd -OPrivacyOptions=noetrn -ODeliveryMode=queueonly -OQueueDirectory=/var/spool/<a href="http://mqueue.in" target="_blank">mq<u></u>ueue.in</a> -OPidFile=/var/run/sendmail.<u></u>in.pid<br>
<br>
It should only put the emails in the queue not also deliver them.<br>
<br>
Even changing <a href="http://sendmail.cf" target="_blank">sendmail.cf</a> to O DeliveryMode=queueonly does not help.<br>
