Changing the SMTP port number in Evolution

I started using evolution email client in Ubuntu. However, my service provider requires me to use a different port for SMTP. When you first check the tab where you set the options for SMTP, you can not find a field about the port number of SMTP. I was looking for a field because Thunderbird has a field for port.
The solution is this :

smtp.hostname.com --> Assumes you are using port 25.

smtp.hostname.com:587 --> You set the SMTP port to 587.

I think this is not a good way to handle ports, but I am happy since I found a soluton.
