[Dovecot] Linking mdbox directories

[Alex Crow]

Hi Timo/list,

We have a scenario in which some email accounts on dovecot (stored in 
mdbox, separate paths for indexes, email, ALT storage and also using SIS 
for attachments, LDAP directory) need their names changed. I know we 
could just change the mail LDAP attribute (and leave mailMessageStore 
alone) so they keep the same directories on disk, but this would throw a 
spanner in the works for our backups.

Would it be possible to create a hard link of the user's directories 
under the new name, and change the LDAP mailMessageStore attribute to 
point to these without stopping and starting dovecot? And after a while 
unlink the original locations? Or would this mess up dovecot's internal 
state?

Thanks

Alex
