error envio smtp desde azure

Rodrigo 1

hola a todos, tengo el siguiente error al intentar acceder a un correo.
Al parecer azure bloqueo la salida y entrada a ese servicio.

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

[SocketException (0x274c): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ]
System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port) +792
OpenPop.Pop3.Pop3Client.Connect(String hostname, Int32 port, Boolean useSsl, Int32 receiveTimeout, Int32 sendTimeout, RemoteCertificateValidationCallback certificateValidator) +187

Thanks for asking question! Could you please confirm if you using a relay Service or are you trying to send email directly from the web application? Check this detailed blog on Troubleshooting SMTP issues/Sending emails from Azure Web Apps

Refer to this official document on How to Send Email Using SendGrid with Azure
