It creates an empty com.freron.MailMate folder within the selected 
folder on the other disk, but does nothing with it - as in no warning 
about copying messages from the current location to the new location, or 
indeed any copying even in the background.

This means that perhaps your other suggestion is the correct one, that I 
created an OSX alias rather than a symlink (I did keep the original 
Messages file as a renamed file just in case). So I will probably do one 
of the offline suggestions I got, or dive right in with another copy of 
the entire mail store and create a symlink (I remember enough Ultrix, 
SunOS, and Solaris but thanks for the command anyway!).

I have also bitten the expensive bullet and gone ahead and bought a 2TB 
SSD for this Mac Pro (I can clone and then boot from the new one etc 
etc) but I’ll work on your solution in the interim so the benefit of 
others who might experience this.
