Not in Mailman.

There are many reasons that a mail may not be received by some members of a list.

1) Spam filters on their machines that trap the mail as spam
2) limitations on your sending server on how many emails you can send to how many people in what amount of time
3) Your server is on an RBL
4) THEIR server is on an RBL
5) They DID receive the mail, they just can't find it
6) DNS issues (yours or theirs)

There are probably other things.
