Respected developers,
I would like to seek your help for the development of an email application for an intranet. The javamail code which i am using need to send mail over the intranet protected by a firewall. Unfortunately, the email sending process is blocked.
I have inserted the mail code in a jsp below. Probably, i need to implement some relay service or use another port but i am not sure. Please, help me find a solution to this problem.
Thank you in advance for your help and consideration.
