Hello everyone,

i am working on the SMTP Email Send Message using labview . i have connected the terminals as suggested in the Context Help and i can run the VI but a keep getting a lot of errors.

Needless to say i cant send the mail .

i have enclosed the vi , shall be grateful if somone can suggest any modifications so that the VI works.

I have also seen the GMAIL.vi but dont want to use as it seems complicated.

Thanks in advance

Hi Sindhurakshak,

I have checked the code and it's working fine for me. I think the problem is with your SMTP server. Please check SMTP server name adn try it it should work.

For shake of testing I have changed the SMTP server name and it works fantastic.

Thanks

hello Pankajusic,

Thanks for reviewing the code.

i was under the notion that the SMTP Server remains the same for a given company . For example, for google it is smtp.gmail.com and the like.

Request you to post your vi with the modifications you have made.

Further , how i can i find my SMTP server name ?

I am using LabVIEW 2011.

Regards

Jalashwa

Are you sure Gmail's server will take SMTP mail? I don't think it does because it would be and easy gateway for spam.

You need your company's e-mail server, and them set up to allow you to give it smtp mail based on that fact they should have already authenticated your PC on their domain.

Hello Ravens Fan,

i delved more into SMTP in Google and found out the following steps:

Open up a command prompt (CMD.exe)
Type nslookup and hit enter
Type set type=MX and hit enter
Type the domain name and hit enter, for example: google.com
The results will be a list of host names that are set up for SMTP

I am attaching a pic of my cmd after executing the steps. I updated the mail server in the SMTP Email Send Message block diagram and i got an error. i have also attached the pic for that

It would be very kind of you if you could guide me through

Regards

Jalashwa

A little off track with regard to solving the specific problem, but to answer RavensFan's point:

Yes, Gmail does allow you to use SMTP. This is how you use other email clients (Outlook, Thunderbird etc) to send/receive things from your gmail account.

(a quick Google confirms this).

In order to use Google's SMTP server function, you must authenticate using TLS/SSL.

The LabVIEW SMTP functions are natively written in LabVIEW and have no support for TLS/SSL.

That document is out of date. LabVIEW 2013 has had email VIs revamed tp support TLS. I've not used these but remember it from the release notes.

Thanks! Good to know. Now I just have to move from LV 8.6 to 2013.

Yeah right before you upgrade from Windows 2000 right? Hey when are you getting a car without a carburetor? Can I have my ball mouse back when you are done with it? Whenever you are done using your CRT computer monitor.

All joking aside I could develop code in 8.6, it isn't that old, but I sure wouldn't want to.

I'm using XP, thank you, but we do have way too many ball mice around the lab.

Most of the CRT displays have passed on; as we've shrunk/downsized over the years we have collected enough FP displays to bring the lab into the 21st century.

My computers are mostly of the Dell Optiplex 745 variety. Talk about carburetors...

I had to look it up, XP came out in 2001, Windows 2000 came out in December of 1999, so I guess one year difference isn't that much. Stating someone is on XP today, would be like stating someone was still on Windows 98 in 2011. While I'm sure there are still Windows 98 machines in use, but I don't know how many are developing new LabVIEW code.
