Auto Email Attachments

[NSearch]

Does anyone know of a way to automatically send email with attachments? I do not want to send the mail by opening up outlook express and sending commands to the application. I would like to have the email sent "in the background".

Any suggestions will be much appreciated.

Thanks,

Stephen

Does anyone know of a way to automatically send email with attachments?

Options:

write a wrapper for the command line utility blat. There may even be one on the site you can use

verbatim or as a starting point.

find a freeware com library supporting the methods you need ( i have yet to find one)

find a dll library and write dllcalls()

Someone has a sendmail udf that uses au3 tcp functions to talk to a smtp server, i haven't looked

at it, but it either has the capability or could be extended to do so.

Remember, if you are doing this w/ a udf a binary attachment must be "encoded" to meet the plaintext

SMTP protocol specification. This adds another layer --- not only do you have to mail the file, you have to prep it to be mailed.

Hi Stephen

I was looking for the same thing and I could not find any example from the forums that would use plain SMTP codes, so I made my own improvements to the original _INetSmtpMail.

I added the file attachment part and an extra mail recipient to the code.

At the moment the code only support one file and one extra recipient.

First I added CC field for one extra recipient. It is possible to add even more recipients. All that need to be done is just send more RCPT TO commands and then also add the recipients to To/Cc/Bcc fields.

With the file attachment, first it needs to be encode to Base64.

Ward had made a good encoder for it, which can be found here: link

After that I added boundaries that would tell which part of the data is the message body and which is the file.

With more boundary fields it is possible have multiple attachments or have the message in HTML.

I hope this works for you who might need it.

Here is the full code:

#include <INet.au3>
#Include <File.au3>
#include <Array.au3>

$smtpServer = "smtp.somesmtpserver.com"
$fromName = "firstname lastname"
$fromAddress = "myname@myisp.com"
$toAddress = "some@address.com"
$ccAddress = "some.other@address.com"
$subject = "_INetSmtpMail2 Test"
$attachment = @ScriptDir & "\Test.txt"
$body = "Testing the email attachment and copy recipient"
$smtpResponse = _INetSmtpMail2($smtpServer, $fromName, $fromAddress, $toAddress, $ccAddress, $subject, $body, $attachment)
$err = @error
If $smtpResponse = 1 Then
    MsgBox(0, "Success!", "Mail sent", 0)
Else
    MsgBox(0, "Error!", "Mail failed with error code " & $err)
EndIf

Hi Scrolli

Thanks for that code, works perfectly. Is there a possibility to have the mail sent with automatic acknowledgement from the recipient? Sorry to ask, I'm a newbie to AutoIt.

Thanks

Bertrand

[scrolli]

You mean the mail will ask for acknowledgement from the recipient that the mail has been received?

Does anyone know of a way to automatically send email with attachments? I do not want to send the mail by opening up outlook express and sending commands to the application. I would like to have the email sent "in the background".

Hi Stephen

I was directed to the Code Cutter Wooltown http://www.autoitscript.com/forum/index.php?showtopic=89321&hl=wooltown&st=0 who has created a whole library of routines that manipulate Outlook where you can set the priority of emails multiple attachments etc etc it is well worth a look. Ant..

[dantay9]

Did you search the forum first? You are looking for what has already been accomplished. Search the forum for SMTP Mailer. There are several mailers out there. All you need to do is cut and paste the functions and automate them instead of using the gui.

[Bertrand]

You mean the mail will ask for acknowledgement from the recipient that the mail has been received?

Yes, this is exactly what I need, but don't know if it is even possible.

Thanks

Hi guys, I am using Scrolli's Library to send email attachments and it works perfectly on windows xp, but on windows 2003 I get an error I traced it to the encoding function but I have no idea how to fix it, can someone please help.

event viewer logs the following:

Faulting application AutoIt3.exe, version 3.3.4.0, faulting module unknown, version 0.0.0.0, fault address 0x01d7f648.

I think this is the offending code, its making a windows call in xp that work but in windows 2003 doesn't like it.

DllCall("user32.dll", "none", "CallWindowProc", "ptr", DllStructGetPtr($CodeBuffer), _

"ptr", DllStructGetPtr($Input), _

"int", BinaryLen($data), _

"ptr", DllStructGetPtr($Ouput), _

"uint", $LineBreak)

Return DllStructGetData($Ouput, 1)

[KaFu]

Are both machines 32bit?

[Charly1r]

yes both machines are 32bit.

[KaFu]

Hmmm, I don't know the specific library / UDF, but I see $CodeBuffer being used. Maybe it's DEP related? Take a look here how I solved that for wards md5 ASM code.

[Charly1r]

The code I am using is the one posted above that scrolli wrote. He is using the INet.au3 library and modified it so it can do attachments.

I will check the suggestion that you posted, thanks a bunch(after I come back from a meeting).

[KaFu]

after I come back from a meeting...

Hungry? Have a meeting, eat cookies ...

[Charly1r]

So... today I log into the server and I get a pop up window for DEP I add the autoit .exe in the exception list and guess what "IT WORKS"

I wish that would pop up when you run the program, but all you get is:

Faulting application AutoIt3.exe, version 3.3.4.0, faulting module unknown, version 0.0.0.0, fault address 0x01d60df0.

Which translated into english means DEP stopped the .exe from running,

I love getting unrelated messages to what is really happening on the server

keeps my job secure.
