Usually, if you're using ignore_target_hosts, verification of the domain fails since there is no valid MX host left for the domain in question and your exim will refuse the domain if used as envelope from. Mails in the queue most likely will bounce or doublebounce/freeze. Depends which returnpath the messages have. Removing them with -Mrm seems reasonable. Can you give some samples of MX entries pointing to bogus IPs other then 127.0.0.1 or ::1?
