Answer Wiki:
I have seen the dreaded 554 in conjunction with being blacklisted. AOL is infamous for throwing the 554 back at you like this: I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program : host mailin-01.mx.aol.com[205.188.159.57] said: 554-: (HVU:B1) http://postmaster.info.aol.com/errors/554hvub1.html 554 TRANSACTION FAILED (in reply to end of DATA command) ? Reporting-MTA: dns; mail.velocity.net X-Postfix-Queue-ID: D2C451770DF X-Postfix-Sender: rfc822; bb10k@velocity.net Arrival-Date: Sat, 26 Mar 2005 12:12:23 -0500 (EST) Final-Recipient: rfc822; Rtb2072@aol.com Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; host mailin-01.mx.aol.com[205.188.159.57] said: 554-: (HVU:B1) http://postmaster.info.aol.com/errors/554hvub1.html 554 TRANSACTION FAILED (in reply to end of DATA command) ? It can also be from other domains. If all your mail is failing just to this ONE domain then you need to get with them to get un-blacklisted. If it is all your email you might have issues with your reverse dns on your mail server. I use this website <a href="http://www.mxtoolbox.com/">http://www.mxtoolbox.com/</a> to diagnose and test my mailserver as well as check blacklists. To remove yourself from the AOL black list visit this site: <a href="http://postmaster.info.aol.com/waters/hvu_request_form.html"> http://postmaster.info.aol.com/waters/hvu_request_form.html</a> and fill out the appropriate form. Reply back with more information and I will continue to try and help.

Can you please provide more details? Is this true for all mail or just some mail? Did it used to work and now does not, or did it never work? What version of Outlook and service pack level? What is your mail system? Exchange or something else? Are all users having the same problem or just you? Your questions is too vague. Please fill in the details. Thanks.
