Dear Philip: Many thanks for your most informative memo. I have restarted sendmail with /usr/lib/sendmail -bd -q90m and now, from what you suggest, I shall bring those 90 minutes down, and will also implement some of your other suggestions. I had forgotten that this was a problem with mailing list management (when I used listproc, years ago, it was a BIG problem). I do have the latest version of sendmail, but probably am not using all its features: Thank you for pointing it out.
