I have a single remote server with one IP address (142.54.186.2) I am using it to host multiple, independent domains. I am working on configuring a single postfix instance to serve mail for all domains (assuming I can successfully rewrite appropriate parts of mail in and out).
From referring to "DNS and BIND" and previous discusssions here and on the postfix users list I have re-examined my domain DNS records to see if I can cover my requirements more easily. Given such a configuration described in the first paragraph, does the following set of DNS records for a domain look look appropriate: # For each domain X.TLD: X.TLD. IN A 142.54.186.2. *.X.TLD. IN CNAME X.TLD. X.TLD. IN MX 10 142.54.186.2. X.TLD. IN TXT "v=spf1 mx -all"
as other suggested: - get rid of the wildcard whenever possible - get rid of the trailing dot in A record - point MX to canonical name of theserver I suggest - replace X.TLD. with "@" (BIND uses this as current origin) the result is: @ IN A 142.54.186.2 @ IN MX 10 mail.example.com. @ IN TXT "v=spf1 mx -all" -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
