Did anyone ever seen this error messages? Than it looks like it starts delivering again! It used to work good and it started all of a sudden i haven't changed nullmailer configuration files,or /etc/aliases ... or any other clue ???? Thanks !!! Debian sarge 3.1 2.6
I guess that the recipient in the first delivery attempt does not exist. have ypu checked your local recipient table?
There must be a file/database that contains all recipient addresses. One of them must be missing there.
