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.
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.
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'
