I used to construct such recipes like this ...

:0:
* ^From:.*(\
      naturallinux@dcemail.com|\
      arnoldbird@cosmicemail.com|\
      usspookslovesystmd@muchomail.com|\
      fredwln2@mail.ru|\
    DUMMYLINESOIDON'TNEEDTOWORRYABOUTFORGETTINGTHEGODDAMNVERTICALBAR)
$JUNK

... but eventually I started getting "procmail: Exceeded LINEBUF"
so I switched to a hack that uses scoring (`man procmailsc`) to
implement unlimited short-circuited alternation (i.e the testing
stops as soon as a condition is true, and there's no LINEBUF limit):

:0:
* 2147483646^0
* 1^0 ^From:.*naturallinux@dcemail.com
* 1^0 ^From:.*arnoldbird@cosmicemail.com
* 1^0 ^From:.*usspookslovesystmd@muchomail.com
* 1^0 ^From:.*fredwln2@mail.ru
* -2147483646^0
$JUNK

This works on 64-bit as well as 32-bit systems.
Unscored conjuncts can precede the alternatives:
