Email Delivery Failures from Hotmail and other Domains
We are having issues where some outside senders are reporting that they are getting delivery failures, including emails sent from Hotmail. No senders from other domains have been willing or able to send us any info on what errors they see on their end. I have run a number of outside tests, and none have reported any problems with the info on our domain or any blacklists that apply to us.
Attached is an email response one sender received from hotmail (accounts of sender and recipient have been stripped):

Thanks for the prompt reply. I'll check that out and post an update.
Setting up a SPF records for your domain would also be a good idea. That would in not getting blocked by various ISP's and email service providers.

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
The IP for your mailserver 98.172.30.147 resolves to "wsip-98-172-30-147.dc.dc.
It should resolve to smtp.emw.com.
You need to contact your ISP and have them enter a reverse DNS record for your mailserver IP (since they maintain the reverse zone for your IP block)
The record should read:
PTR 98.172.30.147 smtp.emw.com
