>Description:
I'm arguing that the load-average checking done by sendmail is obsolete
now. (It's easy enough to configure back in if needed, and makes for
`mysterious' failures if present as is.)
>How-To-Repeat:
1. Try to send mail from a machine that has a constant load-average above
eight.
2. Wait.
3. Wonder why your mail never reaches recipient.
4. Discover source of problem.
5. Curse historical reasons.
6. Decide that load-average checking is obsolete.
