> a message pops up at the bottom of the screen saying that it can't send > because there are too many emails. > Also, in future, please quote anything you see on the screen exactly (and if it only flashes for a second, do it as many times as you need to to see the exact wording) -- if you paraphrase error messages, dialogues, etc. it really decreases the chances a tech support person will recognize the problem. It worked in this case because I managed to make the mental connection between "because there are too many e-mails" and "rate limit exceeded", but if I hadn't happened to have a recent memory of looking at rate limits I would have assumed that the problem was entirely local to Eudora. I would then have Googled something like: Eudora too many messages won't send queued and gone around in circles for an hour or two, because I would've gotten no results at all that mentioned the actual problem. The reason for that is that Eudora and Postfix (our mail server software) don't overlap in the Internet's collection of knowledge, in the same way that horse carriages and jet airplanes don't overlap -- that is, people stopped using horse carriages before people started using jet airplanes, so any Google results about horse problems will not include airplanes. The above Google search will turn up results that are necessarily a decade out of date, because there are no longer any techies using Eudora (and techie users are the ones who post "here's how to solve problems" knowledge on the Internet). An actual count: the above search gives 184000 results, only 5 of which mention Posfix at all -- and none of those 5 are anywhere close to being on the right track for this problem. But if you give me an exact error message, I can Google it as a quote and get results that are exactly relevant to the problem -- Googling "Message delivery request rate limit exceeded" turns up nothing *but* Postfix knowledge, and I would have recognized the problem instantly, even if I had no ideas about it before I started looking. In fact, I don't even have to go to Google -- I can search our own mail server logs for "Message delivery request rate limit exceeded" and it turns up the exact record of what happened when *you in particular* ran into that problem. I most certainly cannot find a paraphrasing like "Eudora says it can't send because there are too many messages" in our logs that way :) ~Felix.
