Hi,<br />
Try creating an intenal relay connector and add the IP address of your helpdesk server to the allowed relay devices. - see: <a href="https://glazenbakje.wordpress.com/2012/12/30/exchange-2013-how-to-configure-an-internal-relay-connector/" rel="ugc">https://glazenbakje.wordpress.com/2012/12/30/exchange-2013-how-to-configure-an-internal-relay-connector/</a><br />

I is located in internal network. I created a receive connector and assigned role as FRONT END, added Exchange IP in it. But still it is not working.

<div>
If it is in internal network then just Use the IP of any Exchange server along with port 25 and do not use any SMTP authentication. Is there any option of SMTP authentication and without SMTP authentication?<br />
<br />
If there is an option of to go without SMTP authenticataion then please go with this optin. In this case you would just need to enter the IP of Exchange server and port 25. &nbsp;It would great of you share the screenshot of configurations in service desk.

I am using exchange 2013 server. &nbsp;There are two Mailbox server. <br />
Our management has decided to use to SERVICE DESK software for ticketing. I have created new email ID for example, support@xyz.com. So if any user is facing problem he will send email to support@xyz.com then this request will be fetched by Service desk. Once service desk fetch the email, I will assign that case to an engineer so here is my problem......<br />
<br />
When I go to assign the ticket, a notification email should go to end user and engineer whom I have assigned the case but this is not happening. If I use gmail.com, then it is working fine.

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Golang, also called Go, is an open source programming language that is a statically-typed language with syntax loosely derived from C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. Go is a general-purpose systems programming language that aims to be efficient both for development and execution with a focus on fast compilation and increased maintainability of large projects. Go was originally targeted at systems programming tasks such as building server/web applications, high throughput middleware and databases.
