I've not been receiving my newsletter and daily news emails this week. When I check my logs it appears that they're being rejected on an SPF failure. Digging deeper it appears that the SPF record for codeproject.com has changed to using IP addresses, but the first SPF record I hit is on maillist.codeproject.com. The maillist domain's SPF record uses hostnames. The hostnames and ips in the two records match, but although the ips reverse-resolve, the names don't resolve. $ dig codeproject.com TXT ... codeproject.com. 3096 IN TXT "v=spf1 ip4:69.10.233.30 ip4:69.10.233.34 ip4:69.10.233.35 ip4:69.10.233.30 ip4:69.10.233.40 ~all" ... $ dig maillist.codeproject.com TXT ... maillist.codeproject.com. 3600 IN TXT "v=spf1 a:mail4.maillist.codeproject.com a:mail5.maillist.codeproject.com a:mail1.maillist.codeproject.com a:mail2.maillist.codeproject.com a:mail3.maillist.codeproject.com -all" ... $ host mail4.maillist.codeproject.com Host mail4.maillist.codeproject.com not found: 3(NXDOMAIN) $ host 69.10.233.34 34.233.10.69.in-addr.arpa domain name pointer mail4.maillist.codeproject.com.

According to wikipedia, SQL was originally called SEQUEL until a trademark collision caused the name change, and most books I've read list Sequel as the proper pronunciation. However, apparently the ANSI standard actually states it's pronounced S-Q-L, so apparently I'm not ANSI-compliant. ;)
