    Hi and welcome to devnet,

    Do you mean compile your application to use that library or use it when deploying your application ?

      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!

        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

          I am using this with Qt 5.7. The email is successfuly sent but then I get this error in the end :

          Server response code: "221"
          Server response: "221 2.0.0 closing connection y144sm8277194wmd.18 - gsmtp\r\n"
          error QAbstractSocket::RemoteHostClosedError
          stateChanged QAbstractSocket::UnconnectedState
          disconneted
          error "The TLS/SSL connection has been closed"

                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?

                            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.
