Thank you in advance. From past experience, I seem to recall that this is due to the pop server (qpopper) failing to do reverse DNS lookups of connecting clients. It logs this message to sy slog, using some level and facility that by default is configured (see /etc/syslog.conf) to be sent to the console. Options to get rid of this message include: - Fix DNS. May not be possible if you don't handle the network where clients connect from. - Reconfigure syslog not to send these messages to the console. - Press Alt+Fn to switch to another virtual console and ignore the messages. I think (not sure, though) that only the first two or so get these syslog messages. - Remove the messages from the qpopper source and recompile. No, I can't think of any reason why these messages would be useful, but then again, what do I know? $.02, /Mikko -- Mikko Työläjärvi_______________________________________mikko@rsasecurity.com RSA Security To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
