Is it possible to send an email from SMTP server, for example from firstname.lastname@example.org, without have the server credential (username and password) inside my code?
I tried one code, it works, but it send from my email account. Not from SMTP server.
I also tested several code but I cant proceed to send the email since it need server credential.
And my Symantec popup error like
Symantec email policy:
Your email message was unable to be sent because your mail server rejected the message.
550 5.7.1 Client does not have permissions to send as this sender
can someone help me pls..?
