Hi!
I'm playing around with postfix 2.1.0 and spam controls.
Just now I'm having trouble with ebay.com: Their server claims to be
e.g. "mx46.sjc.ebay.com" in it's HELO. That address resolves to
10.6.182.166, which is a RFC 1918 private network. Strange enough,
but no real problem.
I've got "cidr" type maps for check_helo_access and check_helo_mx_access
in smtpd_helo_restrictions, both containing a REJECT for 10.0.0.0/8.
Why does ebay hit the helo_mx test but not the helo one? I put
check_helo_access before check_helo_mx_access, and anyway the mail
gets through if I remove the corresponding line from the mx map.
MfG, Ulrich
