ICS 9.3 SVN SMTP Attachment

[chmichael 12]

Hello,

  I get a "attachment.asm" or (.htm if it's html) in the e-mail ICS 9.3 SVN sends.

 

Any ideas ?

 

Thank you

Sorry, you'll need to explain what you are doing with which component.

Hello,

  Here's the function which i send the e-mails

 

function SendEMail(const AArgs: TArray<String>): String;
var
  FSMTP: TSSLSmtpCli;
begin
  FSMTP := TSSLSmtpCli.Create(nil);
  FSMTP.SslContext := TSslContext.Create(nil);
  FSMTP.SslContext.SslMinVersion := sslVerTLS1_2;

  with FSMTP do
  begin
    Host := 'my.emailserver.com';
    Port := '587';
    Username := 'myuser@emailserver.com';
    Password := 'mypassword';
    AuthType := smtpAuthAutoSelect;

    ContentType := smtpHtml; // Important !!! Set it First
    //Allow8bitChars := False;
    //ConvertToCharset := True;
    CharSet := 'UTF-8';

    HdrFrom := 'myuser@emailserver.com';
    HdrTo := 'myuser@emailserver.com';
    RcptName.Text := HdrTo;
    HdrSubject := UTF8Encode(VarToStr(AArgs[0]));

    if Length(AArgs) > 1 then
      MailMessage.Text := UTF8Encode(VarToStr(AArgs[2]));

    OpenSync;
    MailSync;

    Result := ErrorMessage;

    FreeAndNil(FSMTP.SslContext);
    FreeAndNil(FSMTP);
  end;
end;

 

Using the v9.3 SVN version the e-mail which it sends adds an extra attachment which v9.1 didn't:  (either plaintext either html)

There have been no changes to TSSLSmtpCli since V9.0, except to build with other units. 

 

I'd make sure whatever properties are used for attachments are cleared, sorry, don't know which off hand.

I think the error is header for whatever reason it's not the correct eg:

v9.1: Content-Transfer-Encoding: quoted-printable

v9.3: Content-Transfer-Encoding: q

 

Seems 9.3 doesn't apply the correct header values

 

Also Return-Path: <> is empty (in both v9.1 and v9.3)

The line:

 FEmailBody.Add('Content-Transfer-Encoding: quoted-printable')  {AG}

is unchanged in 15 years.

 

But I will test the sample to make sure it works, in a few days time.

I've just tested the OverbyteIcsSslMailSnd sample in V9,3 and it's sending content and attached files as expected with the correct encoding headings. 

 

But it is not attempting to send HTML emails.

 

BTW, the component expects String content and will convert to whatever encoding is specified, no idea what will happen if you encode UTF8 and it then encodes it again.

Depends on the version of the Delphi. Code Page aware versions of Delphi is going to do as expected UTF-16 to UTF-8 and on assignment back from UTF-8 into UTF-16.
