Next message: Sandy Drobic: "Re: Two postfix servers on two independent VPSs, protecting each other?"
Hi, I have got postfix working with mysql but in my /var/log/mail.log
file I see this :
warning: dict_nis_init: NIS domain name not set - NIS lookups disabled
I know this has already been answered here by :
"remove the references to nis from your config.
postconf | grep nis "
But first I would like to know what a NIS domain is, and if I need to
set it or not ... I don't like just deleting options without knowing
what they do...
Thanks in advance
Richard
