Announce List messages not getting sent


I created a WordPress blog for a third party. I added a subscription form using Dreamhost’s form code; subscribing and unsubscribing works great. But when I try to send a test message to the list (which currently contains precisely one email address – mine), it apparently never gets sent.

I log in to the Dreamhost control panel, browse to Mail, then Announce Lists, click the Mail icon beside my announce list, complete the message form, leaving the default current time for Send Announcement At, and click Submit Announcement Now. The message gets added to Announcements Being Sent Now table, but I never receive a message, and the Last E-Mail Sent column never gets updated.

What am I missing?


And now three test messages, submitted hours apart, were finally sent within 1 minute of each other. Was this all just a server hiccup?
