The following was forwarded to me yesterday.

>Dear Email List Manager;
>
>In the upcoming months, Yahoo! Mail will become more aggressive
>in its acceptance of SMTP connections and will begin denying
>connections by IP address when these connections do not conform
>to Internet standard practices. To continue uninterrupted
>access and prioritized delivery, you should ensure that your
>email address lists are well maintained. If you are conforming
>to these standards, then these changes should only affect
>you positively. We anticipate you will see improvements in
>delivery times and in available connections.
>
>If you want to ensure that your email is prioritized and
>your SMTP connections are not blocked, please:
>
>   Reply to this email with:
>     o Your current list of IP address(es) from which your
>       mailings are sent.
>     o The domain names of your "From" address(es)
>       of your mailings.
>     o Contact email address (will be used periodically to
>       update your IP and From addresses).
>
>   Remove email addresses that bounce.
>     Bounces are an indication that the mail could not be delivered
>     because the user does not exist, no longer exists, or is unable
>     to accept your email. Well managed lists remove addresses
>     that generate bounces. A particularly popular technique
>     for managing bounces is to use VERP to identify the recipient
>     address that has failed.
>
>   Maintain accurate reverse DNS information
>     for your mail servers. Yahoo! Mail makes extensive DNS checks
>     for each connection and an accurate reverse DNS will ensure
>     prompt processing of your connection and email.
>
>   Pay attention to the responses from our SMTP servers.
>     The SMTP protocol defines response codes that tell your
>     server what to do next. In particular, our server will send
>     "500" SMTP response codes to indicate problems
>     that you need to investigate. For example, if you send email
>     to too many recipients in one connection or to too many
>     invalid recipients, our servers will respond with a "500"
>     range SMTP code, indicating a permanent error.
>
>   Don't send unsolicited email.
>     Make sure that all email addresses are confirmed with an
>     opt-in process that ensures the recipient wants to receive
>     your list.
>
>   Provide an unsubscribe email address in each mail you send.
>
>Thank you for your cooperation.
>Sincerely,
>The Yahoo! Mail Team
