Re: Domain can't send to Hotmail

Multiple accounts on both ends have been tested.

Did your customers check their Junk/Spam folder using the webmail
interface to their Hotmail account?

If Hotmail has blacklisted your domain, it doesn't matter what a Hotmail
*user* has listed in their white- or blacklist. That e-mail blocked by
their mail server never reaches the recipient's mailbox, so any rules
defined by the recipient can't be exercised against an e-mail that never
reached their mailbox.

You'll have to contact Microsoft as to why they decided to block your
domain. Hotmail is notorious for NOT send back non-delivery report
(NDR) e-mail notifications to the sender. This has been reported by
postmasters in several forums. They accept the e-mail, they reject the
e-mail, it never touches the recipient's mailbox, and they don't send
back an NDR. If your customers don't want Microsoft to vaporize e-mails
while in-transit AFTER Hotmail has accepted the e-mails (i.e., the
sending mail host gets back an OK status), they'll have to use a
different e-mail provider. This happens with both paid and free
accounts there because the problem is Hotmail dropping the e-mail.

I found out about all the postmasters bitching about Hotmail's
vaporization of *accepted* e-mails when I started reading up on SPF and
then found articles on how Microsoft doesn't do it correctly. That also
led to postmasters noting that Microsoft has several documents of their
own on how to "properly" deliver e-mail to Hotmail, as if following the
RFC standards for SMTP weren't sufficient for Microsoft. Tis the
problem with a company that chooses to define their own proprietary
e-mail standards and doesn't want to fully comply with any that they
don't define. If your company is using SPF, go read about Hotmail's
screw up with it at http://www.google.com/search?q=%2Bhotmail+%2Bspf.
To read the Experts Exchange forums, you'll need to register (free).

Apparently Microsoft will collect a ransom where a company can pay
Microsoft to get on some list that helps to ensure delivery of their
e-mails but Microsoft won't guarantee delivery for that ransom.
