connect to 127.0.0.1[127.0.0.1]:10024: Connection refused

[xplanet]

I've made a zentyal update and after that I'm getting following error messages:
connect to 127.0.0.1[127.0.0.1]:10024: Connection refused
and
delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused

The bad part is that the whole mail service is stopped.


cat /var/log/zentyal/zentyal.log | grep mailfilter

As a temporary workaround, you could deactivate mail filtering in mail configuration and restart mail service.
At least you will have mail delivered.

Hello,

if you upgrade to the last version of zentyal-users you will get likely a more explicit error.

Since the message error is very terse I have not idea of what is going on but we had recently problems with losing LDAP schemas. If you see that this is the problem, you can try to fix it with this command:

Code: [Select]

sudo -s # this will prompt your for password to get superuser access
perl -MEBox -MEBox::Global -e'EBox::init(); $mod = EBox::Global->modInstance('mailfilter'); $mod->performLDAPActions(); 1'
/usr/share/zentyal-mailfilter/mailfilter-ldap update
/etc/init.d/zentyal mailfilter restart
exit # exit superuser account
And always, like Christian says, you can disable the mailfilter to at least deliver mail

[xplanet]

I've already deactivated 'Antivirus enabled' and 'Antispam enabled' in 'Mail Filter > SMTP Mail Filter' (MailFilter/Composite/Amavis) but the only change is that, all messages Status in Queue Manegement is: "connect to 127.0.0.1[127.0.0.1]:10024: Connection refused" now.
I tried to 'Attempt to deliver all queues mail', none of them delivered.

[christian]

disabling anti-virus and anti-spam is not enough because mail will still be delivered to port 10024.
You should better "unselect" the "enabled" check-box so that mail filtering is not involved anymore.
Then you will have time to investigate further while mails are delivered.

[xplanet]

You mean to to deactivate mailfiltering features but not the module, don't you?
Where can I do that?
'Module Status' > 'Mail Filter' would disable the module.

I read this old thread: http://forum.zentyal.org/index.php?topic=2339.0 but didn't solve my problems.

[christian]

I don't know which Zentyal version you run (you don't tell in your message) but in 2.2, when configuring mail filtering, you have multiple options:
- enabling or not mail filtering
- enabling or not anti-virus
- enabling or not anti-spam

my point was to say: if you just removed spam and anti-virus but kept mail filtering "enabled", this is not enough. Rather disable mail filtering (in mail filtering configuration).
The point is not to stop, remove or deactivate mail filtering "module" but to configure it so that it is not involved in mail delivering process.

[xplanet]

Sorry to forgot. It is Zentyal 3.0.19

There is no any option at: 'Mail' > 'General' > 'Mail filter options'
only this text: "As long mailfilter module is enabled the mail server will use the filter it provides"

[christian]

Sure but you should have such options in mail filtering section isn't it ? 

[xplanet]

There is 'Mail Filter' section with:

        SMTP Mail Filter
        Antispam
        Files ACL

but there is no option to disable the mail filter.
In 'Mail Filter' > 'SMTP Mail Filter' > 'General' there are: 'Antivirus enabled', 'Antispam enabled' and 'Service's port' 'Notify of non-spam problematic messages' only.

[christian]

So, too bad 
I can't help further as I don't run Zentyal 3.0 and it will not help telling you that Zentyal 2.2 permits to selectively enable or not mail filtering 

[xplanet]

Maybe it is changed in Zentyal 3.0
I had no better idea, so I disabled the Mail Filter module in 'Module Status'. After that there was 'Filter in use' option at 'Mail' > 'General' > 'Mail filter options' which is set to 'none' now.
Now the mail server can send and receive mails at least.

It's time to repair the mail filter. Before that I go out for a coffee, I didn't sleep too much at night.

Thank you, I've two questions:
Do I need to backup first or it's a safe command?
Can I use this command with disabled mailfilter module? Or I have to re-enable it before?

[xplanet]

I've got several mails like this:
"Subject: Cron /usr/bin/freshclam --quiet

sh: 1: /usr/share/zentyal-antivirus/freshclam-observer: Permission denied"

Does it have any connection with mail filter problem?

The non-zarafa accounts never worked on this server. They can send e-mails but can't receive any. We don't use them because we need only zarafa mail service so it wasn't a big problem. However spam@ and ham@ accounts are not working, they are non-zarafa accounts. May it cause problem in mail filter?

[ost]

I think that i have the same problem:

Is there any chance to solve this for using the mail-filter?

(i use the core version 3.0.20 with all updates)
