Normally sendmail (v8?) detects the .procmailrc in your home,
so you don't need to put anything awkward in your .forward.
This is not correct. Sendmail still doesn't ship with Procmail
preconfigured, you have to reconf it using the right FEATURE. Unless
this was changed +very+ recently. (8.9.4?) Certainly not true for any
old v8 in any case.
OK, I stand corrected.
