Topic: Mailing list security doesn't work

We have several mailinglists, but when we set it to moderators only still everyone can send emails to this address.
Also when we disable the mailinglist it still works.

In the iredapd.log we get the following error:

Error while importing plugin module (maillist_access_policy): No module named maillist_access_policy

Hope anyone can help me with this.

With kind regards

Re: Mailing list security doesn't work

What version of iRedMail and iRedAPD are you using?

Does file "/opt/iredapd/src/plugins/maillist_access_policy.py" exist?
All enabled plugins are listed in /opt/iredapd/etc/iredapd.ini, plugin name is same as file name under /opt/iredapd/src/plugins/ directory (remove ".py" extention).

Re: Mailing list security doesn't work

I think i found the root cause: incorrect file permission.

Try below command and then test it again:

# chmod -R 0700 /opt/iredapd/

Re: Mailing list security doesn't work

This seems to solve the problem.

But when I send an email as a moderator I don't get a verification email, is it possible to build this in.

Also if I send an email is a non moderator I don't get an email telling me I'm not allowed to send e-mails to this mailinglist so I'll never know if the email is sent or not.

Why we need a verification email?

If it's not allowed, client will get a error message with their MUA.

I think my boss wants this as an extra security measure.

This works indeed, was a little problem with my private email

One more problem I found:

We have an email account hcn with an alias hypotheken,
when they try to send an email to a mailinglist as hypotheken the get a message not autherized.
But it is not possible to add hypotheken to the moderators, could this be solved or do we need to change al those email addresses?

It's iRedAPD issue, it doesn't query user alias at all.

Try to fix it this way:

* Open /opt/iredapd/src/plugins/ldap_maillist_access_policy.py
* Find below lines:

        searchAttr = ['mail']
        searchAttr = ['mail', 'listAllowedUser']

* Add 'shadowAddress' in them:

        searchAttr = ['mail', 'shadowAddress',]
        searchAttr = ['mail', 'shadowAddress', 'listAllowedUser',]

* Restart iRedAPD.

It should work as expected.

Re: Mailing list security doesn't work

For as far as I can see it still doesn't work,
the part if ldap_maillist_access_policy.py looks like this:

    if policy == 'membersonly':
        # Filter used to get domain members.
        searchFilter = "(&(|(objectclass=mailUser)(objectClass=mailExternalUser))(accountStatus=active)(memberOfGroup=%s))" % (recipient, )
        searchAttr = ['mail', 'shadowAddress',]
    elif policy == 'allowedonly' or policy == 'moderatorsonly':
        basedn = listDn
        searchScope = 0     # Use SCOPE_BASE to improve performance.
        # Filter used to get domain moderators.
        searchFilter = "(&(objectclass=mailList)(mail=%s))" % (recipient, )
        searchAttr = ['listAllowedUser']
    else:
        # Policy: membersAndModeratorsOnly.
        # Filter used to get both members and moderators.
        searchFilter = "(|(&(|(objectClass=mailUser)(objectClass=mailExternalUser))(memberOfGroup=%s))(&(objectclass=mailList)(mail=%s)))" % (recipient, recipient, )
        searchAttr = ['mail', 'shadowAddress', 'listAllowedUser']

Shouldn't there be a change at the moderatorsonly part too?

Re: Mailing list security doesn't work

Can you please set 'log_level = debug' in /opt/iredapd/etc/iredapd.ini, restart iredapd, resend testing mail, and post related log in /var/log/iredapd.log? So that i can know the detail about LDAP data.

Please give me some more time to dive into it. Thanks very much for your patience.

Re: Mailing list security doesn't work

Hi, @veldsink.

I improved iRedAPD today, it will log plugin debug message now, could you please try again?
You can checkout source code here:
http://code.google.com/p/iredmail/sourc … po=iredapd

* Backup old iRedAPD first (/opt/iRedAPD-x.y.z/), and then just replace old iRedAPD by new version.
* Be careful that file owner should be "iredapd:iredapd".
* Set loglevel to debug and restart iredapd service.
* Monitor /var/log/iredapd.log, and post related log content here to help troubleshooting.

Re: Mailing list security doesn't work

Hi, @veldsink.

Improved iRedAPD again, it will bypass user aliases now.

You can checkout source code here:
http://code.google.com/p/iredmail/sourc … po=iredapd

* Backup old iRedAPD first (/opt/iRedAPD-x.y.z/), and then just replace old iRedAPD by new version.
* Be careful that file owner should be "iredapd:iredapd".
* Set loglevel to debug and restart iredapd service.
* Monitor /var/log/iredapd.log, and post related log content here to help troubleshooting.
