This is one for the qpopper mailing list, but to save you some trouble, the "not pemitted" is what qpopper reports when the client end of the connection has gone away and it finds it's writing to a closed socket. It gets seen on all kinds of platforms and is not a BSD issue, nor (usually) an OS configuration issue. This almost always indicates a buggy POP client which is failing on some message, and/or a client which is running AV software which transparently "hijacks" POP connections in order to scan them. In either case you need to see what's going on on the client end. qpopper is merely more verbose about reporting this than most POP servers. -- Clifton -- Clifton Royston -- cliftonr@tikitechnologies.com Tiki Technologies Lead Programmer/Software Architect "I'm gonna tell my son to grow up pretty as the grass is green And whip-smart as the English Channel's wide..." -- 'Whip-Smart', Liz Phair
