I currently host about 70 virtual domains and all can send to Yahoo. None of them have their own IP, but all of them are cnamed in my dns to my actual mail server. Don't know if this info can help you resolve the issue. That's just how I'm doing it.

Let's see how fast Yahoo changes their song.

Yahoo apparently responded. I do not know if this is accurate or not but I do know that those clients of ours that have their own IP are not having problems, yet. I have read of individual companies having the same problem using Exchange but cannot verify their email configurations to tell why. "Thank you for writing to Yahoo! Mail. We cannot systematically exempt your mailings from our SpamGuard technology since the IP address of the server appears to be a shared domain mail host and have multiple clients sending email. We will maintain the current information in our database as it is configured. This allows delivery of your mailings to oscillate between the Inbox and the Bulk Mail folder as Yahoo! users choose. Please keep in mind that our SpamGuard technology will continually monitor user feedback pertaining to emails coming from your mail server(s), and as such, the user feedback we receive will be one of the factors that influence where your emails are most appropriately delivered. Our studies have indicated that when users see messages incorrectly categorized, they notify us within hours of delivery. We do recommend that if you maintain several clients or company lists (especially for an ISP/ASP/ESP) to segregate your clients to different IP addresses. This ensures that users are marking each company on its own merits. User notifications to us may become hazy should they see both spam and legitimate mail from the same IP. In cases like these, the end result will likely be that spam will override the legitimate mail. If you implement significant changes to your mailing practices, feel free to contact us again. You may refer to the Help page below for some information and general guidelines that we have found to be effective in maintaining good mailing lists:" At 09:21 PM 5/20/2007, you wrote: Sounds like Yahoo is graylisting. -Dave Doherty Skywaves, Inc. 97 Webster Street Worcester, MA 01603 508-425-7176 ----- Original Message ----- From: Krishna <mailto:[EMAIL PROTECTED]> To: [email protected] Sent: Sunday, May 20, 2007 9:52 PM Subject: Re: [IMail Forum] Yahoo bounces I had the same problem few months back, Yahoo server treats all emails as spam and rejects the emails however if the same email is being resent then it goes through so make sure in your email server you set to re-try for 20 to 30 times. After i did this all yahoo emails are going trhough.
