Hi, We are trying to migrate away from Indy because of the lack of modern OpenSSL dll's and no OAuth support
Now we implemented the first part: Moving from TIdSMTP to TSslSmtpCli.
At first it looked fine, but at the moment we went to production a lot of SSL errors occurred: SSL handshake failed - No error returned, connection closed unexpectedly, but not all the time.
Out application is a ISAPI module, with datasnap, where multiple clients can give the server the order to send emails. Some of these need to be send asynchrone, some synchrone.
I came across the following topic and if there is any application which runs completely in thread, it is an isapi module.
How should the sending of email be implemented in such a case?
Thanx in advance,
Jan
