    Nevermind, I got it fixed. Turns out you shouldnt rename the dll file after building it. Its name should be the same as specified in TARGET

            Did you check whether your server uses an outdated protocol that is either not supported anymore or disabled by default for security reasons.

                    Did you install and openssl on your window machine ? Is your Qt built with SSL support ?

                      @fab_ said in Simple TLS/SSL supported SMTP client for Qt5:

                      Hello everyone.

                      this post is long long ago, so does this is still work for current new version Qt?
                      and is there better SMTP Qt lib?

                        Hello!

                        It's both I guess.
                        I want to use the functions that lib gives me in my code for my application.

                        When i deploy the application i usually have to provide all neccessary dll files in the same folder (libmysql.dll) for example. So no static linking if thats what you're referring to.

                        If you look at the github page of my first post. There is an example of its usage right on the front page. I'm trying to achieve to get this example to run properly.
                        https://github.com/bluetiger9/SmtpClient-for-Qt

                        After I made my first post I spent the rest of the night tinkering with it and I managed to get something going:

                        Following this;
                        https://wiki.qt.io/How_to_create_a_library_with_Qt_and_use_it_in_an_application
                        I saw that MinGW (I use MinGW)creates a .dll and a .a file. I copied both those files in the folder containing the project where there supposed to be used. I also copied the header files in the same folder.

                        Here is my .pro file:

                        QT       += core
                        QT       -= gui
                        
                        TARGET = SMTPEmailTestDLL
                        CONFIG   += console
                        CONFIG   -= app_bundle
                        
                        TEMPLATE = app
                        
                        win32:CONFIG (release, debug|release): LIBS += -L$$PWD/ -lSMTPEmail
                        else:win32:CONFIG (debug, debug|release): LIBS += -L$$PWD/ -lSMTPEMail
                        else:unix: LIBS += -L$$PWD/ -lSMTPEmail
                        
                        INCLUDEPATH += $$PWD/
                        DEPENDPATH += $$PWD/
                        
                        SOURCES += main.cpp
                        

                        This actually enabled me to build and run the programm as seen on bluetiger9's github front page.

                        But, upon running it either terminates with return value -1073741515 or I get the message that "The process to debug couldnt be adressed: wrong parameter"

                        Weirdly, although receiving those messages, the programm sometimes actually sends an Email out to my gmail Account (be it with a wrong timestamp) as intended, but sometimes it just doenst.

                        So I might've done something wrong on the way.
                        I'm sorry if the information I'm giving is somewhat blurry. I appreciate you taking some time for this SGaist!

                        anyone ever used libcurl to send email to smtp server?how many milliseconds it need for sending mail one time?is it fast enough to send email by libcurl in mainThread?

                        i tried this one, it works. but it's slow, as it needs about 3000 milliseconds for sending email one time.

                          @opengpu would you please stop spamming every e-mail related thread?

                          you have a concrete question, so ask it. provide example code so others understand your problem.

                          Regards

                          Qt has to stay free or it will die.
