time should *never* move backwards. OSes (and programs) assume time is
always moving forward. Injure your VPS provider.

:I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem.

:Reading the TimeMovedBackwards article on the Dovecot wiki, and the kernel mailing list thread referred to on it, it would seem quite apparent that this is caused by a failure of the gettimeofday() function to reliably return the correct value.

:If anyone has any advice as to how I could proceed to fix this (I currently have a watch on the Dovecot service which restarts it after any failures) or how I should best phrase this to get it resolved 'upstream' by the VPS provider, I would be very grateful.

:Thank you,
