How do I manipulate an email with "too many recipients" and turn it into several emails?
My email is to 900 of my fellow alumni. My server has a limit of 500 recipients. (I don't know Thunderbird's limit.) So I cannot find a way to access my list of recipients, OTHER THAN ONE AT A TIME. What I would like to do is to be able to pull 90 out and create ten new emails with 90 recipients each. I do not want to do another three days of cutting and pasting.

Thunderbird's limit is "approximately 60", if you list them as discrete addressees.
Put them into a Mailing List and there's no known limit, at least as far as Thunderbird is concerned. Your ESP or ISP may have their own limits that still apply.

Another approach is to generate one message per addressee, using a mail merge. There is an add-on that can do this, though I prefer using Libre Office with its own mail merge and smtp client.
