[nycbug-talk] gmail & spamd
lists at genoverly.net

gmail has always been a moving target for me and my OpenBSD spamd. I
read a little snippet on misc@ that seems to help. It looks like SPF
in TXT records in DNS are getting popular. gmail lists their smtp
servers in that record so..
$ dig gmail.com TXT +short | tr "\ " "\n" | \
grep ^ip4: | cut -d: -f2 > /mywhite_gmail
..will put all gmail mail servers out to a file. I can then add that
table my pf rules. I could probably add all the mail giants to this
table too. ..aside from allowing all gmail mail into my server.. [grin]
Is there any danger in this?
