That's a good question and one that I'm trying to pinpoint (hence the ticket placed with Yahoo) but, as you have found with other mails within the same grouping being delivered straight away, it all points to Yahoo's grey-listing policy.
It must be putting huge overload on their servers that they are deferring mails by the million, for multiple retries at the delivery end — it's complete nonsense!
What I am seeing in this trend is that the worst affected mails are either those being generated in mailing lists or server apps, and/or mails being forwarded (by account-based rules) to Yahoo, e.g. some of my clients receive mail from externally to the server, or receive internally from their domain, then they have a forwarding rule to their Yahoo account — always held in the mail queue. In such forwarding examples, if they also forward to Gmail or Hotmail etc., no problem ...
Anyone else with a
dedicated server care to comment or contradict, then please step forward?
