I'm not familar with the INDY SMTP component. I want to send a mail with INDY and Office 365. Here is a nice topic which helped me a lot: What do the SMTP Indy component security and authentication properties do? But I did not figured out how to use SASL. Office365 adress is smtp.office365.com with port 587 and TLS. So I added an SMTP and an OpenSSL-IOHandler to my form and setted the properties. But I didn't work, the app is just freezing. I need to know how to use SASL with Office365.
Thanks.
Office365 only supports the LOGIN
SASL on TLS port 587.
The following code works fine for me when I just tried it (all of these settings can also be set up at design-time as well):
setting the TIdSMTP.AuthType
property to satDefault
, which uses the SMTP AUTH LOGIN
command:
var
idSMTP1: TIdSMTP;
begin
idSMTP1 := TIdSMTP.Create(nil);
try
idSMTP1.IOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(idSMTP1);
idSMTP1.UseTLS := utUseExplicitTLS;
TIdSSLIOHandlerSocketOpenSSL(idSMTP1.IOHandler).SSLOptions.Method := sslvSSLv3;
idSMTP1.Host := 'smtp.office365.com';
idSMTP1.Port := 587;
idSMTP1.AuthType := satDefault;
idSMTP1.Username := ...;
idSMTP1.Password := ...;
try
idSMTP1.Connect;
try
idSMTP1.Authenticate;
finally
idSMTP1.Disconnect;
end;
ShowMessage('OK');
except
on E: Exception do
begin
ShowMessage(Format('Failed!'#13'[%s] %s', [E.ClassName, E.Message]));
raise;
end;
end;
finally
idSMTP1.Free;
end;
setting the TIdSMTP.AuthType
property to satSASL
and using TIdSASLLogin
, which uses the same SMTP AUTH LOGIN
command:
var
idSMTP1: TIdSMTP;
idSASLLogin: TIdSASLLogin;
idUserPassProvider: TIdUserPassProvider;
begin
idSMTP1 := TIdSMTP.Create(nil);
try
idSMTP1.IOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(idSMTP1);
idSMTP1.UseTLS := utUseExplicitTLS;
TIdSSLIOHandlerSocketOpenSSL(idSMTP1.IOHandler).SSLOptions.Method := sslvSSLv3;
idSMTP1.Host := 'smtp.office365.com';
idSMTP1.Port := 587;
idSASLLogin := TIdSASLLogin.Create(idSMTP1);
idUserPassProvider := TIdUserPassProvider.Create(idSASLLogin);
idSASLLogin.UserPassProvider := idUserPassProvider;
idUserPassProvider.Username := ...;
idUserPassProvider.Password := ...;
idSMTP1.AuthType := satSASL;
idSMTP1.SASLMechanisms.Add.SASL := idSASLLogin;
try
idSMTP1.Connect;
try
idSMTP1.Authenticate;
finally
idSMTP1.Disconnect;
end;
ShowMessage('OK');
except
on E: Exception do
begin
ShowMessage(Format('Failed!'#13'[%s] %s', [E.ClassName, E.Message]));
raise;
end;
end;
finally
idSMTP1.Free;
end;
Update: Office365 no longer supports SSL v3, you must use TLS v1.x now:
(idSMTP1.IOHandler).SSLOptions.Method := sslvTLSv1;
