One of us seems to be very confused. You might need to read the book "DNS and BIND" or something similar. Do you really mean your 'hosts' file, as in '/etc/hosts'? Please phrase your question more clearly. What operating system are you using? Please say exactly what and where the files are. SPF is not (and BIND is not) configured by changing the 'hosts' file although you can give information to a local resolver that way, as a short-cut, instead of configuring a nameserver to do so. > Currently hosts file looks like: > > Mydomain.com 172800 IN TXT "v=spf1 mx -all" > Mydomain.com 172800 IN SPF "v=spf1 mx -all" > Mydomain.com 172800 IN MX 10 Mail.Mydomain.com > Mail.Mydomain.com 172800 IN A vvv.xxx.yyy.zzz > > Is this correct? Is this the complete file? What is the file, and where is it in the filesystem? Are you running the nameserver (the software is called 'BIND', the binary is called 'named')? How is BIND to find the file? Are there some other files which give information about the domain, such as '/etc/named.conf'? You probably need to tell us about them. The string "v=spf1 mx -all" is OK as an SPF record whether the record type is TXT or SPF. It is better if you specify IP addresses instead of 'mx' (it's more efficient, as it reduces the number of queries required). > FYI not using DNSSEC It makes no difference to the SPF records themselves. -- 73, Ged. _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
