Just try Mailenable diagnostic utility

It will show you exact error so that you can proceed with your investigation

thanks IgorG,
I am working with prallels pleask panel v9.3
Wondering if this panel have a way to tell me the reason why it is still there in the que
invalid e-mail? or detect as spam, or mail size too big?
without ssh into the server
