Hello,

I have met the issue, I have removed one user from smartermail server, but when sending email to allias (to all domain users) it returned: 

Remote Server returned: 'RecipientDoesNotExist'

I have tried to create the same user and then removed it, but this not helps, then i create again and leave how it is, but today i met the same situation on another user (which was removed from smartermail server a months ago).

Maybe someone haev met this before?

Thanks in advance.

Best,

Greg
