Stopped as Invalid Recipients

Hi,
I was just looking at my Incoming Mail Summary and was wondering what "Stopped as Invalid Recipients" means. Are these mails dropped by my filters in the CLI?
Thanks.

Re: Stopped as Invalid Recipients

No, the "Stopped as Invalid Recipients" represents messages dropped by your LDAP Accept Query process.

By setting up LDAP recipient validation, the Ironport is freeing up resources on your mailserver and performing the recipient on the Ironport appliance.

For example, say a message arrives on the Ironport appliance and is addressed to:


recipient email address: blahblahblah@yourdomain.com

The Ironport ldap process will take the recipient email and ask your LDAP Server/domain controller/active directory if this is a valid user in your domain:

If it's valid, the system will process the email like normal.

If it's invalid, depending upon your Accept query setting, it will either drop or bounce that individual message. You can see this setting by going to "Network > Listeners". Select your incoming or inbound listener and go to the LDAP queries section at the bottom.

Re: Stopped as Invalid Recipients

Hi Kluu,
Thanks for you response. I don't have any LDAP servers set up. I do have some filters configured to drop mail for certain recipients. Could this be what I am seeing? If not where are messages dropped by filters recorded? I can see them in the logs but the "Stopped by Content Filter" category shows zero:

Wed Feb 27 00:21:26 2008 Info: Message aborted MID 26551349 Dropped by filter 'drop-bad-recipients-3'

Re: Stopped as Invalid Recipients

Given that you don't have LDAP configured, these are most likely people trying to send mail via your mail server for a domain that isn't in the RAT.

ie, users who are attempting to use you as an open relay.

Thanks Doc.

Do you know in which category mails dropped by filters are included in?

You should see a 'Stopped by Content Filter' which covers this.
