One of my client received a failure notice. "Remote host said: 550 Requested action not taken: mailbox unavailable or Anti-spam Action"
I already put their email add in whitelist but still cannot send email until i delete the anti-spam in my firewall Juniper SSG-350M.
Anyone knows how can i solved this problem without deleting the anti-spam in my firewall.
