Creating SQL server CLR for SMTP emails

Question

0.00/5 (No votes)

See more:

I have created a CLR that is in vb and is very basic:
It send out smtp emails and has one import:
Imports System.Net.Mail

I created the assemble successfully and I can run the CLR Code but when I do I get the following error message below:

Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

What I have tried:

I am trying to load the assemble system.net.Mail but I can't find the dll anywhere

What dll clr should I load?
I am trying to keep the vb code with no references.

You'll need to create the CLR assembly with UNSAFE permissions to send email.

Thank yo for the quick response on this and for your answer. I was trying to avoid using UNSAFE permissions because that allows someone to gain access to the file system and other resources on the server. I thought this was a security vulnerability.
Again thank you for the response
