Having Problems using "SMTP Email Send Message VI"

[Controls_Engineer]

I am using the "SMTP Email Send Message VI" to send email messages whenever there is an alarm on the system.

I started using the example program.

I am able to send a "test message" sucessfully, but when I try to send a string constant that describes the alarm condition on the system, the email is never received.

For example, if I send "FP1 Burner" as the message string I receive the email, but if I send " FP1 Burner Disabled", the email is never received.

Is there a limit on number of characters that you can send in the message using this VI? Does the message string have to be in a particular format only?

The VI error out indicator does not show that there is any error.

Please help me use this VI correctly.

Thanks,

Archana

Hi Archana,

This seems to work fine for me:

Could you post the VI or a screenshot for us to look at?

Here is a snapshot of the VI that I am using to send an email.

I never receive the email.

Please let me know what needs to be changed so that the email will work.

Thanks,

Archana

1. Do you have a corporate spam filter active? The filter could be throwing your email away as a "spoofed" email. Check your spam folder and reply back. (You can also test this by sending to a personal email account that you know does not have 
2. Does "error out" return an error? (I'm guessing 'no', since you would have included that info in your post. Doesn't hurt asking.)

I checked with the Network Administrator and he said that there is no Spam filter for our emails. I am sending these messages to two addresses one is my company email address and the other is my personal gmail account address. When it works, I receive emails on both my accounts, if it does not work I do not receive it on any of the accounts.

The problem is, it works for some text messages and it does not work for some, and I am not able to figure out the reason for this.

The 'error out" does not return any error.

This problem is very strange.  It should not matter what text you send.  But since no one has a clue, I would take a message that doesn't work, eliminate one character at a time and send the message to see if it is one particular character that is causing the problem.  Perhaps the underscore (or space or whatever it is between the time and date) is the culprit.  I would at least start with non-alpha characters.

The built-in SMTP VIs will not work with GMail, regardless of what you try to send. This has come up many times in this forum. GMail requires authentication, and the SMTP VIs do not handle authentication. If your internal server also requires authentication, then you cannot use the LabVIEW SMTP VIs. If you are on Windows you can use .NET.

But the op claims that it does work for some text.  So it can't be an authentication problem.  Still strange that text makes a difference since it should not.

It works with gmail. I have tried using that.

As I had mentioned eariler it wirks with some text mesaasages and it does not work with some. So, I don't think "authentication" is the problem.

Does the problem have anything to do with how often you send the emails? If some emails are getting through and some are not, I suspect a problem with the email server and not your code. The body of the email should not matter, unless like I said before, there's some spam filter active.

Can you test another sender email account on a different host?  So, you can send outbound email via your GMail account?
