How are you configuring it? You can share images

Shivam.thaker · July 19, 2023, 4:03am

I have server Ip and port number.
Only these details are shared by the IT team.
Telnet with the server work shows a connection established.
I and return this string.

Note we have a custom exchange server on which Outlook works,
We are not using Microsoft Office 365 or any other service.

Update:
as mentioned by @max_morais_dmm I tried using smtp lib and it was able to successfully send the mail.

Which ports are you using?

Shivam.thaker · July 20, 2023, 4:36pm

Port 25

Leo_Sarmiento · July 20, 2023, 4:45pm

You are using domain or IP.
In Incoming Server and Outgoing Server you are using

Shivam.thaker · July 21, 2023, 5:32am

Same IP & Port for Both Incoming and outgoing.

Leo_Sarmiento · July 21, 2023, 2:07pm

To send mail you must have a domain name.
You cannot add the same port in incoming and outgoing.
Incoming
If it is POP3 the port is 110
If SMTP the port is 993
Outgoing
The port is 25, 465 if you use SSL and 587 if you don’t use SSL.
