I am working with Java Mail API, i am getting this strange error: "Initial Access check failure"

My configuration looks fine, URL, user, pwd, etc. Just cannot figure out why this message comes up.

Answer 1

I got this issue and resolved it by providing access to my server and sender email id on SMTP server. SMTP servers are restricted as to which server can send email from what sender email id. Contact with your SMTP administrator have them grant permission to your server ip and sender email id.
