 This way, conditions are logically ANDed. You want logical ORing:

:0:
* Sender:.*(address1 at address1.com|addresss2 at address2.com)
mail.box

 Check out the procmail(1), procmailrc(5), and procmailex(5) man pages,
 procmail's regexp handling is slightly different from other progs.

 A lockfile "locks" the mailbox file against multiple concurrent access.
 Imagine you'd have two processes trying to write the same file at the same
 time ... havoc. See man lockfile(1).

 So, alway make sure to use the traing colon in mailbox delivery recipes.

:0:
* condition
mail.box
