Hi there, I have a SSIS package worked fine till yesterday, but the send mail task failed today with the info below: Error: 0xC002F304 at Send Mail Task, Send Mail Task: An error occurred with the following error message: "Failure sending mail. System.Net.WebException: Unable to connect to the remote server System.Net.Sockets.SocketException: A connect request was made on an already connected socket 205.248.106.64:25". I didn't find much information with the info above. Does anyone have any idea what could be the cause? Regards, Di Di Yang

If it worked fine before, so the send email task shouldn't have issue. Does any scripts exist in your package ? If any scripts exists, you may need to check your script to make sure you close the connection before you trying to connect the remote server to prevent there's any connection has connected to remote server. Another way is to restart the remote server if it's posibble. For example, there's a connection between local server and remote server, you will meet error if you send a connect request again in the same thread. Please vote if it's helpful and mark it as an answer!

it seems like the issue caused by the connection to the SMTP server, try to telnet/ping into your server. if the send mail task status is failure, sent the mail again. Let us TRY this | My Blog :: http://quest4gen.blogspot.com/
