Hello,

I am using Jenkins version 2.235.2 on Windows server 2019. I was using the email-ext-plugin version 2.68 and was using it to send emails.  I upgraded to version 2.73 and now I cant change the SMTP port number to something else besides 25. Hence, emails are not being sent out anymore. Steps to reproduce:

1. Click on Manage Jenkins -> Configuration
2. Under the header “Extended E-mail Notification”, Change the value of SMTP Port to 465
3. Save your changes and exit
4. Click on Manage Jenkins -> configuration
5. Under the header “Extended E-mail Notification”, the value of SMTP Port is still showing 25

 I was trying to set this number to 465 since I am using Gmail.

In addition to that, email-ext-plugin version 2.73 is now showing the SMTP Password in plain text. It used to be all *** previously. I am not sure if this is a major issue, but might be a security risk.  I have attached screen shots
