Solved by changing all the mysql-virtual* .cfs to 127.0.0.1. I'm really unsure what triggered this problem however, as things have been fine and I certainly didn't edit any configs. I initially noticed my server was unresponsive, seemingly due to mysql being pegged, rebooted it and then noticed no mail flow. Bizarre to say the least.
