Sending e-mail with CDO and SSL

[Rick Lipkin]

To All Concerned

I found this thread in the FW Spanish forum and noticed in one of the links the use of SSL and CDO to send e-mail

viewtopic.php?f=6&t=13175

Within the thread was a link to a VIsual FoxPro forum which gives an example of using CDO and SSL..

http://www.portalfox.com/index.php?name ... me=Printer

I have not tried the above code, but I thought it was worth a look for those who use FWH to send e-mail thru their apps.

Let me know if anyone is successful using the FoxPro code.

Thanks

I am trying this out. Here is my code for the send function:

        IF LEN( aTabMail[06] ) > 0
            For nEle := 1 To Len( aTabMail[06] )
             :AddAttachment( ALLTRIM(aTabMail[06][nEle] )) // := AllTrim( aAttach[ nEle ] )

       Return .F.
   
    END

Return( .t. )

 

On my non-SSL service, it works fine. However, when on an email account requiring SSL, we see the following error from the Send( )

DISP_E_MEMBERNOTFOUND

I've tried a websearch and found there was a thread on this in the Five Win forum, but what worked for someone else didn't fix it here. The values in the TabMail array are accurate.

I hope someone can succeed with this problem.

In the code I supplied, all three of those items are referenced properly.

Tim

[James Bott]

Tim,

Are you using the code supplied here?

viewtopic.php?f=3&t=15843&p=82081&hilit=gmail#p82081

Have you checked to see if your firewall is blocking the port?

Have you tried increasing the timeout value?

Regards,
James

[TimStone]

James,

Yes, that is where the code is from.

The settings are identical to Outlook, which is working, so the port is not blocked.

The timeout value is set to 30 but the error reports back much more quickly.

The question is, what element returns that error on :Send( )

Tim

[James Bott]

Tim,

I sent a test program to your email. Please let us know if it works for you.

Regards,
James

[James Bott]

Tim,

>The settings are identical to Outlook, which is working, so the port is not blocked.

I think this is where the problem may be. You MUST use port 465. Is that the port the Outlook is using? Is that the port your sample code is using? If not, try port 465.

I tried port 25 and it errors out, but port 465 works fine.

Regards,
James

[James Bott]

Tim,

May I suggest using a mail object rather than an array--it would be much easier to read.

Instead of:

aTabMail[02]
aTabMail[03]
aTabMail[04]

You would have:

oTabMail:From
oTabMail:To
oTabMail:Subject

It is so much easier to work with.

Regards,
James

To send emails using ssl, at least from xharbour, you must link the open ssl lib: tipssl.lib

On your app directory you need to have these .dlls present:
libeay32.dll
ssleay32.dll

There are a few threads on the xharbour forum explaining how to build the .libs and where to download the .dlls from.

A simpler way to test if you have the open ssl libs linked, is trying to http to an https address. Once everything is in place, you can use xharbour's native emailing funcs.

Hope that helps,


Reinaldo.

Can you provide a link to the location of the information and DLLs you mentioned?

I seem to remember, when I looked into this before, that you had to purchase some kind of security certificate? I expect this would be for each user?

I'm not sure how you can use FW's native email classes since they don't support SLL thus there are no native settings for SSL. At the least it would seem that you would have to subclass the TSMTP class to add the SLL settings.

Regards,
James

[reinaldocrespo]

download open ssl from:
[url]
http://slproweb.com/download/Win32OpenSSL-0_9_8y.exe
http://www.microsoft.com/downloads/deta ... 4B9F2BC1BF
[/url]

Open ssl is an open source project. Nothing to purchase. The web server wishing to have an https address, needs to purchase a security certificate. Not so the user that connectes to it. Email server requiring ssl authentication, must have purchased their security certificate. Otherwise, they could not be offering/requiring ssl connections.

FW TSMTP native email does not send using ssl. You would have to change the class. To send emails using a server that requres ssl authentication, you would have to use xharbour native emaling funcs that inherit from xharbour's Tip class + have the ssl libs linked in. Again, there are a few users on the xharbour's ng that know a lot more than I do. I was helped by Luiz Rafael Culik from Brazil. It took me a while to understand, but since it has been working, I haven't looked at that again. It just works.

Tim and friends ..

Since I started this thread .. I wanted to make sure that we end it on the solution ..

Tim .. I cut and pasted this solution from your ( other ) thread that spawned from this one .. Please verify this is your solution to implementing CDO and SSl ..

Many thanks!
