Hi everyone, 

 

I'm using SmarterMail Enterprise 14.2.5711. I have the following question:

 

Suddenly, an account in the domain to send mail in the local alias duplicate mail. Here is the log SMTP records from the system.

Message in spool is more than 500 only mail sent from account admin to alias support. I do not understand the error is caused by client or by the system . When I temporarily lock the account, but this situation has occurred. When I delete an alias, the other condition is no longer appear.
