Does Sending email via external SMTP from my web application (asp.net mvc) using .net framework class ( System.Net.Mail ) require opening any outbound ports from windows firewall on my server (which port must be opened)
i am experiencing a success trials to send from my local machine (development) but failed to send on the production live server (with no errors or exceptions thrown)
using the same mail server info and recipient email:
- on my local machine .. it sends with no errors and received at the recipient side
- on live server .. it sends with no errors but never received at the recipient side
so what’s wrong
