GillesL.

Can someone point me out in the right direction please. I used the following code in 2 different programs. One works the other fails because the "Document" file does not get created... const Document : string = 'c:\temp\rcvdata.txt'; function TForm5.PostURL(URL, HeaderKey, HeaderValue, Data: string): string; var S: TStringList; begin if FileExists(Document) then DeleteFile(Document); S:= TStringList.Create; try if HeaderKey <> '' then begin SslHttpCli1.ExtraHeaders.Add(HeaderKey + ': ' + HeaderValue); end; SslHttpCli1.SendStream := TMemoryStream.Create; SslHttpCli1.SendStream.Write(Data[1], Length(Data)); SslHttpCli1.SendStream.Seek(0, 0); SslHttpCli1.RcvdStream := TMemoryStream.Create; //not to sure about this see HTTPDocBegin SslHttpCli1.URL := Trim(URL); SslHttpCli1.ContentTypePost := 'application/json'; SslHttpCli1.Post; S.LoadFromFile(Document); Result:= S.Text; Memo1.Lines.Add('DATA SENT:'); Memo1.Lines.Add(Data); Memo1.Lines.Add('RESPONSE:'); Memo1.Lines.Add(Result); finally S.Free; end; end; procedure TForm5.SslHttpCli1BeforeHeaderSend(Sender: TObject; const Method: string; Headers: TStrings); begin Memo1.Lines.Add('HEADERS:'); Memo1.Lines.add(Headers.text); end; procedure TForm5.SslHttpCli1DocBegin(Sender: TObject); begin FByteCount:= 0; SslHttpCli1.RcvdStream := TFileStream.Create(Document, fmCreate); end; procedure TForm5.SslHttpCli1DocData(Sender: TObject; Buffer: Pointer; Len: Integer); begin Inc(FByteCount, Len); end; procedure TForm5.SslHttpCli1DocEnd(Sender: TObject); begin if Assigned(SslHttpCli1.RcvdStream) then begin SslHttpCli1.RcvdStream.Free; SslHttpCli1.RcvdStream := nil; end; end;

First app migration to Rest was easy and works. One issue but I think it is server side. Working on 2d app, looks good so far. So much easier! Thanks for the help.

The problem was with th TSSLContext. I duplicated the settings from the sample code and everything worked. The issue was in the SSLOptions I am not sure which one was causing the problem: [sslOpt_MICROSOFT_SESS_ID_BUG,sslOpt_NETSCAPE_CHALLENGE_BUG,sslOpt_NETSCAPE_REUSE_CIPHER_CHANGE_BUG,sslOpt_MICROSOFT_BIG_SSLV3_BUFFER,sslOpt_SSLEAY_080_CLIENT_DH_BUG,sslOpt_TLS_D5_BUG,sslOpt_TLS_BLOCK_PADDING_BUG,sslOpt_TLS_ROLLBACK_BUG,sslOpt_NO_SSLv2,sslOpt_NO_SSLv3,sslOpt_NETSCAPE_CA_DN_BUG,sslOpt_NETSCAPE_DEMO_CIPHER_CHANGE_BUG] I do appreciated the suggestion about using Rest instead and I will rewrite my code to do so. Thanks for the response.

Windows 10, icsv864, Delphi 10.4, VCL app using SMTPClient... I have an app which runs in the background and must send an email (unattended) when a certain event takes place. From time to time the app stops because the component is not smtpReady: procedure TCustomSmtpClient.CheckReady; begin if not (FState in [smtpReady, smtpInternalReady]) then raise SmtpException.Create('SMTP component not ready'); end; Is it possible to have a quiet exception, no need for user to click OK, and have the app recover and continue to work. Anyone has experience with something like this: procedure TCustomSmtpClient.CheckReady; begin while not (FState in [smtpReady, smtpInternalReady]) then begin Application.ProcessMessages; //not sure if it is warranted Sleep(1000); //maybe 100 would be sufficient end; end; Or maybe a better solution...

Thanks. I did not realize that the property "State" was published, which makes it easier so I do not have to modify the source.

I developed an app under Windows 10. If I try to run it under windows 7 when I try to send an email I get this error on connect: RequestDone Rq=0 Error: Winsock - Interrupted system call Is there something to change on the old windows 7 box? Any help would be appreciated.

Fixed the problem... it was a simple port issue.

I am having a problem using TSslSmtpCli (v8.55) in a console app (cgi) under windows 10 and Delphi Tokyo (10.2.3). The problem is I can not assign a procedure (created as a TSmtpRequestDone) to the event OnRequestDone since procedures and methods are not compatible. Using a Form provides a mechanism to do so but creates another problem since the app is a console app and I end up with a run time error 216 as the app terminates. Is there any other way other than creating a new component using TCustomSslSmtpCli as a base.

I followed the example and used the TSslSmtpCli component instead and it works fine. Thanks for the input.

Thanks. I will give it a go.
