which means BLACKLISTED?


As far as I remember on the forum there is a note that this value (in earlier versions of the program) is wrong, and it was suggested not to pay attention to it.

I try to send an answering machine to myself and received such an error

BLACKLISTED This email is blacklisted. Sending is denied!

Important! I do not see the fact of receipt of the letter by the mail system, while the subscriber is unsubscribed to the black list due to an error
I actually have such errors in companies, for the same recommendation we did not pay attention to it. Thought it was a program error - but the letters did not actually go away
