I understood your question but you didn't understand my answer.
sme only has one user set, applicable to ALL hosted domains.
If you create a user called
user1
then that user WILL receive email for all valid domains
eg
user1@domain1 > user1
user1@domain2 > user1
user1@domain3 > user1
The correct way to manage email for multiple domains is by using the pseudonyms panel to direct email to appropriate users at appropriate domains.
eg
user1@domain1 > johnb
user1@domain2 > paulw
user2@domain1 > marys
user2@domain2 > sueb
etc etc
In this case do not create user1 or user2 directly as a user account, but as a pseudonym directed to a user account or group.
