Hi, I am using vchkpw and have relaying open to only a few IP's. What does this error mean.? I have searched the web and can't find anything. The system has worked fine for quite awhile. Is this a problem with vpop not adding the virtual domain correctly for relaying.? and help or direction of were to look would be great.
