SMTP with authentication

cdmmaui · Post by **cdmmaui** » Thu Aug 24, 2006 10:25 pm

Hello,

Is it possible to use TSMTP class and send email automatically (without Outlook) with from user authentication? If so, can you provide sample code?

Thank you,

Darrell,

There is a modification for FWH Class TSmtp but it looks as it does not work properly on all circunstances.

As Rene suggested, you may use funcky SMTP component as it supports authentication.

Hi Antonio,

Where can I obtain the funky SMTP component?

Thank you,

Darrell,

Anyhow, here you have the Class TSmtp from FiveWin modified to support authentication by Luis Krause:

We use MarshallSoft's SEE32 (32-bit) DLL
It supports authentication, and it's easy to use.
If anyone wants to test it, download from www.marshallsoft.com, and
ask me for the wrappers.

Kind regards
Evans

Hi Evans,

I own SEE32 also but I was told it does not work with FWH? Did you get it to work with FWH?

Hi cdmmaui (sorry, but it's a difficult name)

Yes, we use SEE32 since our program was in 16 bit. Later on, we converted to 32-bit DLL (SEE32.DLL), and of course, now with xHarbour and FWH, we use the 32 bit without any changes to our code.

I can email you some samples (abstracts from our code to send emails), including the authentication (some newer version of SEE32 supports authentication too, and we have it).

It's not difficult to use it, especially because I have created a great wrap-around code in one simple .PRG file where I am using the SEE32.DLL without having to load/unload it all the time.

We are very satisfied with the library, although sometimes -very rearly- we get a winsock error - but like I said, it's very limited.... for example in about 200 machines that it is used, I have found 3-4 problems only, and those were finally solved, because our clients did not use the correct setu-up (pop3 and smtp) for sending email... It was so simple to fix the problem, just copy and paste their setup from outlook or netscape, etc. !

Anyway, if you need some code to get you going with SEE32.DLL in FWH/xHarbour, please send me a personal email I could reply to. This applies to all of our friends who would like some help in using this specific DLL.

Regards
Evans

Hi,

We successfully do "plain" (mime encoded) authentication.

Below an extract from our modified smtp class:

Code: Select all

#define ST_INIT       0
#define ST_CONNECTED  1
#define ST_RESET      2
#define ST_MAILFROM   3
#define ST_RCPTTO     4
#define ST_DATA       5
#define ST_SENT       6
#define ST_QUIT       7
#define ST_DONE       8
#define ST_ERROR      9
// AS 08/09/2005 New status code for authentication
#define ST_AUTH       10

We use the Matteo Baccan internet classes for xharbour!

It works fine, and the source of the project is open.... You don't have to depend of dlls or libs.. Try this, I'm sure you will not regret.

http://www.baccan.it

There you can download a zip format file that comes with the source and some samples, the class is called xHarbour TSocket (1.05) and it englobes other minor classes. Try looking at the TSmtp Class which allows you to use authentication and many other options.
The Matteo Baccan's website is unstable sometimes, so if you want I can send you the file by e-mail..

Best regards..

Hi Evans,

Does the SEE32 library support sending HTML as well?

R.F. · Post by **R.F.** » Thu May 24, 2007 8:55 pm

Funcky is the way to go, support everything, authentication, htm support, and e-mail existing routines.

A little pricy, but worth the price.

Ok, dumb question - which one? for C++ for Xbase++ ?

R.F. · Post by **R.F.** » Fri May 25, 2007 8:31 am

Ollie:

Look for the COM component (Delphi, VB, BC++) works via OLE, here a sample:
