  4. New Webmail ignoring ReplyTo header

    I operate a web hosting system and over 1,500 of my users have Yahoo! email addresses.

    Forms on their websites direct enquiries to them. The forms are sent from a single email address (eg info@mydomain.com) but have the enquirer's email address in the ReplyTo header.

    When my client replies to an enquiry, their reply should go to the email address specified in the ReplyTo header, not to my address (info@mydomain.com).

    However, I've recently been receiving their replies instead of the intended recipients. This is only happening when the client is using Yahoo! mail, not any other provider,…

  11. Yahoo servers are following links in messages

    Yahoo servers are following links in messages
    My firm sends emails to yahoo.com clients with embedded html links that permit the recipients to Accept or Decline.

    yahoo.com clients will click one of the hyper links in the email, then our system logs their response as Accept or Decline, and logs the IP Address.

    We are seeing various Yahoo servers (note list below):

    We are periodically, seeing bulk processes of yahoo.com clients emails which are processing both the Accept and Decline client responses, in each email message.

    The yahoo servers are bulk processing these email messages upto 6 weeks after the…

  12. Why can't you allow mailing list sending?

    I'm trying to send a work email to a mailing list address: your system classifies that as an SMTP abuse.

    Your service is amateur, pure ****; I will gladly use Gmail for my needs from up to now, and I will give you a VERY bad feedback to friends and colleagues.

  16. Does yahoo support SPF records with Macros as per the RFC? Getting temperror.

    All other mailbox providers support SPF macros, however, emails sent to yahoo are getting: "Received-SPF: temperror (encountered temporary error during SPF processing of domain of example.com)"

    We are using spfproxy.org's service to help us manage many included SPF records. Is this a know issue? SPF passes with all other email providers.

  20. "Blocking" an email/spam no longer works, you have to "show full header" and block the IP address

    "Blocking Spam" doesn't seem to work any longer. I get MORE mail from the ******* Russian Federation, yet Yahoo can't block that? Gimme a BREAK! If they can send it Yahoo should be on their toes to BLOCK that ****. I've started blocking IP addresses, which has worked pretty well, but Yahoo needs better filtering tools for such nonsense.

    And in 2016 these ******* MORONS are still sending SPAM?
