Email problem "An error occurred while sending mail (550 Administrative prohibition )"

Added by Jürgen Weiss about 9 years ago

Hi,

when sending a test mail I get “An error occurred while sending mail (550 Administrative prohibition )”. I am using the same mail account/settings with various other packages such as Wordpress (on the same server) and have no issues, but from OP I do have.

My SMTP settings are as below. I have checked through many forum messages and can’t see anything wrong with them. I tried with “SMTP_AUTHENTICATION=plain” as well and other changes to the SMTP settings, but now running out of ideas.

Thanks and regards, J.

OP 5.0.16
