ADDITIONAL INFORMATION
I am seeing this error while trying to sync an IMAP folder. The INBOX folder works fine, but the Spam folder (a sub-folder of INBOX) is throwing this error in the Akonadi logs:
org.kde.pim.imapresource: Fetch job failed "Fetch failed, server replied: A000010 BAD Error in IMAP command FETCH: Invalid messageset ( 0.001 + 0.000 secs ) . "
org.kde.pim.imapresource: ""
org.kde.pim.imapresource: Fetch job failed "Fetch failed, server replied: A000015 BAD Error in IMAP command FETCH: Invalid messageset ( 0.001 + 0.000 secs ) . "
org.kde.pim.imapresource: ""

By the way, this worked until about seven days ago.

The webmail interface for the host (webmail.dreamhost.com) works correctly.

I started getting this on two accounts. The said accounts work fine in Thunderbird (the spam folder syncs fine).

Other IMAP accounts (non-dreamhost) are working fine.
