Title: 550 5.1.1Recipient address rejected: User unknown in virtual mailbox table
Post by: exodustech on February 19, 2019, 09:03:56 pm
Hi, I have about 30 users within 4 virtual domains. The very last email user z...@... generates a bounce back to the mail sender with the following error: 550 5.1.1 <"emailuser">: Recipient address rejected: User unknown in virtual mailbox table. If I add any new users I get the same error. Now any user virtual domain not dependant can email the user and the user can reply. It is just any email address not originating in our mail server trips the above error.

I have tried deleting the user and tried adding it again. Also adding new user ends with the same issue. I would like to thank any one that can help in advance!  In the webadmin dns server area and added all virtual domains to the domains section. I have also added the domain names in the host file next to 127.0.0.1. Still same error.

Thank you,
Doug.
