Our company has a call centre which pc's are locked down (no access to internet, email, office applications) and there is a need for them to be able to log support tickets from their own machines.
I have created a VB Windows forms application which grabs some info from the user (name, email, extension, subject and description of the issue) as well as system information collected from WMI.
I intent to send all of this information to our helpdesk via email, the sys information would enable us to identify hardware problems and such.
However when trying to send a mail. it just doesnt work.
We have a smtp relay which allows for anonymous email relay and does not require user credentials.
Once i get the basic test mail to work i will start populating the mail with the information i get from the user. However the mail is currently throwing exceptions and not sending at all.
Note I am an absolute beginner when it comes to VB and .net as i come from a linux / php background
Below is my code:
