And I tried to reply:
A mail from you could not be delivered. See below for details.
Recipient:
<dillon at apollo.backplane.com>
Remote-MTA: 216.240.41.2
Reason:
550 5.0.0 You cannot send email directly from a DSL or CABLEMODEM or other mass-media host, you must
instead relay it through your ISP's mail host. Sorry, there is too much spam coming from customers
of your ISP and your ISP is not doing a good job of stopping it. If you are a legitimate mail
domain you must have a correctly configured reverse DNS.
The sendmail.org website states from which IP address a reply will
most likely come (yes, it's static, no, PacBell won't delegate
reverse DNS).
PS: thanks for the patch, it will be in 8.14.3.
