MailScanner Stopped! - won't start

wjweb · Post by **wjweb** » 06 Aug 2009, 05:07

As you can see from the screen dump below.. there 1441 pieces waiting to be delivered.

I recently updated CP on the server and so suspect that has something to do with Mailscanner reporting as stopped and being unable to restart it.

I tried the suggestion /blog/index.php?itemid=419 (I am not allowed to post URLs)
That didn't work and the suggestions in the "Help! MailScanner isn't working/Mail isn't being delivered. What do I do?" FAQ.

Below is the result. Any ideas?

Did you try force installing the File::Temp perl module or running /scripts/checkperlmodules?

wjweb · Post by **wjweb** » 06 Aug 2009, 08:37

Why should I do this? And how exactly? I have made no changes to the system other than updating MSFE and WHM/cPanel.

Why is MailScanner not working? Does it need this PerL module? If so this must be a new requirement as MS has worked without fail since it was installed over a year ago.

So perhaps this module is no longer required for WHM/cPanel and was removed? I recently upgraded to cPanel 11.24.5-R37946 - WHM 11.24.2. Is MailScanner not compatible with this version of WHM/cPanel?

It is just very frustrating to have an error that has no resolution but impacts e-mail delivery to all clients. I see this as major service impact that a fix should be made available for immediately. Please provide some clarity to your response.

Thanks.

Our MailScanner install/configuration is certainly compatible with the version of WHM/cPanel you are running. However, we cannot cater for every possible issue introduced by a cPanel upgrade or an OS upgrade (often due to poor configuration of the OS update system). We do our best to help clients fix problems as soon as we are aware of them. As you are the first person to report this problem at this time, it doesn't look like it is a widespread issue so it's not something we can provide a blanket fix for. Obviously MailScanner requires this perl module since it is reporting the problem in the error message.

To force install this perl module do this in ssh (logged in as root):

/scripts/perlinstaller --force File::Temp

Then restart MailScanner.

If that doesn't fix it, in ssh do:

/scripts/checkperlmodules

And then restart MailScanner. You might also need to manually upgrade MailScanner using the full perl module check (the upgrade in the WHM front-end does not do the full perl module check). This is how to do it:

rm -Rfv msinstall*
wget http://www.configserver.com/free/msinstall.tar.gz
tar -xzf msinstall.tar.gz
cd msinstall/
sh install.sh

Select option 1 for full perl module installation.

Also, you can always disable MailScanner while you are working on it so that email coming into the server will bypass MailScanner. Re-enable it once MailScanner starts sucessfully.

Thanks Sarah I did disable MS after it wouldn't restart but I need those 1141 e-mails to be delivered. So will need to get MS working again. I will what you suggest and let you know.

wjweb · Post by **wjweb** » 06 Aug 2009, 17:07

So I re-enabled and tried the first two options but still it won't start.

It does this:
Restarting MailScanner...

Shutting down MailScanner daemons:
MailScanner:[FAILED]
Waiting for MailScanner to stop..
Starting MailScanner daemons:
MailScanner: [ OK ]

The 'taillog" shows this:

I am weary of the 3rd option as it removed MS and as I said I have mail in the MS queue that I don't want to lose. Is this mail still likely to get processed?

It looks to me like MailScanner DID start successfully:

Starting MailScanner daemons:
MailScanner: [ OK ]

If you didn't see any further errors after that, it should be OK. The failure to stop MS is not necessarily a problem unless you are seeing other errors.

The log excerpts you include don't show any mailscanner lines so it isn't helpful. It shows you are running spamd, which I assume you enabled after you disabled MailScanner, since you should always disable spamassassin in cPanel if you are running MailScanner. You should now disable spamassassin again and try restarting MailScanner at the command prompt in ssh to see if there are any errors.

Hi Sarah, got an entirely new error this time:

root@alpha [~]# service MailScanner stop
Shutting down MailScanner daemons:
MailScanner: [FAILED]
Waiting for MailScanner to stop..
root@alpha [~]# killall -9 MailScanner
MailScanner: no process killed
root@alpha [~]# service MailScanner start
Starting MailScanner daemons:
MailScanner:

**** ERROR: You must upgrade your perl IO module to at least
**** ERROR: version 1.2301 or MailScanner will not work!

[ OK ]
root@alpha [~]#

Also nothing I have done has gotten MS to show that it is "started" in MSFE. And mail is not getting delivered when its enabled.

I guess you'll need to force install the perl IO module, then.

/scripts/perlinstaller --force IO

From a brief search of the mailscanner mailing list it appears this whole thing might be an issue with the CentOS 5 perl install - is that the OS you're running?
