Has any way to detech a sending MailMessage been rejected?

when i sending a mail,sometimes will receive a PostMaster message which said “recipient address rejected :users unknown in local recipient table”, is any way to know a address is available before mail sending?


thanks

Hi Pyntia,


There is no such method available that can pre-check if the destination email address is existent or not. If the issue is not persistent, it may be related to some specific email server or specific email, and hence, doesn’t seem to be an issue with the API.

oh, i got it. thanks
