posted October 26, 2019 10:07 AM I am receiving an Error Event 10053. I am still testing with the Sample program provided with SMTP v2.13.1. This Error Event is firing, and then a Progress Event is immediately firing with a "2.0.0 Service closing transmission channel". If the remote mail server is closing the channel, why am i getting the Error Event first? And how can i avoid it? It seems like the Progress Event is delayed. This is the last few Progress Events logged to the Debut.Print: *********************************** On Progress: Reply = Operation = Send Status = Send Count = 316 Size = 488 *********************************** On Progress: Reply = Operation = Send Status = Send Count = 316 Size = 488 *********************************** On Progress: Reply = 2.0.0 OK <MN2PR14MB3359AB51B09594CC21B63CC3DC640@MN2PR14MB3359.namprd14.prod.outlook.com> [Hostname=MN2PR14MB3359.namprd14.prod.outlook.com] Operation = Send Status = OK Count = 0 Size = 0 Error: 10053 An established connection was aborted by the software in your host machine, possibly due to a data transmission timeout or protocol error. PowerTcp will close the connection when this error is encountered. *********************************** On Progress: Reply = 2.0.0 Service closing transmission channel Operation = Logout Status = OK Count = 0 Size = 0 |

posted October 30, 2019 4:14 PM Thank you for your post. We have tried, but are unable to reproduce your issue. If this is a TLS 1.2 connection it could be the server is immediately closing the connection without sending the close_notify. In that case, the component would receive the server's response to the Logout command, but not yet fire the progress event since it's waiting for the server to send close_notify. If the server does not send close notify we would report the progress and the 10053 error would still be thrown by winsock because it had a pending read waiting for the close notify when the connection was closed by the server. As the client-side there really isn't much we can do to rectify the issue. Please send an email to support@dart.com, referencing this post if you have additional questions. All the best, Jamie |

posted October 31, 2019 10:15 AM Thanks Jamie, I am testing with 3 different mail servers, and one of them is TLS 1.2 encryption. I'm not sure now if that is the one that was resulting in the error. I basically added some progress steps, and if my step is > x, then i just ignore the Error 10053. Thanks again, Tim Snelling |
