Yes. It tells me your outgoing MTA is verifying each recipient address
and taking 30 seconds for each one. I.e it is processing a maximum of
120 recipients per hour or 2.5 hours for one post to a list with 300
non-digest subscribers. Then your out queue gets hoplessly backlogged.

You can look at some of the performance FAQs at
<http://wiki.list.org/dosearchsite.action?searchQuery.queryString=performance&searchQuery.spaceKey=DOC>
for some ideas, but this is an MTA configuration issue.
