So many possibilities:
- wrong address for recipient (most common for my users)
- mail is in recipients spam/trash
- recipient has broken filtering
- spam filters
- sender blocked by recipient or SPF
- ...

Assuming you are on Linux, use "dig" to confirm your target has valid MX
records, e.g.:

$ dig claws-mail.org mx
[snip]
;; ANSWER SECTION:
claws-mail.org.    10799   IN      MX      10 mx.colino.net.
[snip]

So, mail sent to this list actually goes to Colin's server...

You should do some basic checking with your recipients... they, or their
email providers may have logs...

Not that I know of.  You could open an enhancement request; but I'm not
sure that would get on anyone's priority...
