starbase,

SpamFilter will not allow to relay emails to anything except the domains listed in your "Local Domains". This is done to prevent spammers from using your server as an open relay to send emails out to the internet.

There are two exceptions to this, which allow your legitimate users to relay their emails thru SpamFilter out to the internet.

Case #1 - you implement SMTP Authentication. In this case, all users who authenticate successfully are whitelisted and able to relay out to the internet thru SpamFilter.

Case #2 - any IP address (or subnet) added to the "Excluded Domains /IP" list is whitelisted and is allowed to relay emails thru SpamFilter. Please note that only IPs are allowed to relay from that list. Any domain names you add to the list (as whitelisted email "from" addresses) are still not allowed to relay.

So in summary, both of the above exceptions cause the senders to be whitelisted, so no spam rules are applied to them, and they are also able to freely relay. Please note that is you purchased the anti-virus plugin, all emails will still be scanned for viruses.

starbase,

Based on your screenshots, assuming the username is "Oscar6", as it is indicated by the "cn" attribute, your "Search Mask" in SpamFilter should be:

(cn=%0:s)

However from your screenshots I do not see a "password" attribute. Without a password, users cannot be authenticated. Are you certain that passwords are being exported into LDAP?

starbase,

When you exported the accounts from merak to LDAP, did you export both the username and the passwords? If so, what is the full DN path to the users? This would be something like:

ou=users,dc=your_domain,dc=com

and the users will be identified by something like:
uid=starbase

The DN to the "starbase" user could thus be for example:

uid=starbase,ou=users,dc=your_domain,dc=com

SpamFilter will need a "Search Base", which is a DN underneath which all user accounts will be located (ou=users,dc=your_domain,dc=com in the example above), and it will also need a "filter" that lets it know how the user accounts are identified - (uid=%0:s)   in the example above.

If you can describe your LDAP structure a bit more in detail we can try to help further.

Hi,

I've spam filter isp installed and testing. It really works and stops almost all spam. but I have a problem:

I use a Merak Mail server as my relay smtp and account managing. This server has LDAP exportation so I can export my users to a LDAP and here is the problem:

I need to use SMTP Auth, when I connect spam filter isp to the LDAP it connects, but I can't ask any user/password because always return 'Account failed: User not found'.

I assume that the mask search can be altered, but when I try to change it to search to accomodate the values of my LDAP it always shows 'Account failed: Credenciales no válidas'

I need to use spam filter isp with this merak mail server because I have almost 500 users and I can't think on migrate to another mail server.

Can anyone give me a hand? Any idea?
thanks a lot and king regards.
