I use the gmail smtp with StartTLS. With jNet 1.75 it works without error.
I am using the smtp class inside a background worker as private, I set all the properties in the initialize method of the background worker and create the message (recipient, body) and send it in another thread.
The thing is that if I use jNet 1.75 no errors are thrown and the message is sent, if I use 1.76 the above error raises so it must be of something that changed ... or from something i am not doing right
