Update lazy expunge documentation example

[listerr]

I could not get this example to work:

2026-05-03T11:33:38.013704+01:00 turing dovecot: imap(user@example.com)<207022><ZMaTWOdQtKzURTGS>: Error: Mailbox Trash: Laz
y-expunge transaction failed: Mailbox Trash: UID 94164: lazy_expunge: Couldn't open expunge mailbox: Failed to open mailbox
 .EXPUNGED: Invalid mailbox name: Begins with hierarchy separator

Then the ACL didn't apply for some reason.

Added fts_autoindex = no, as this seems like a good idea to avoid unnecessary fts indexing.

Updated config example works on 2.4.3

Hi, the problem is that your separator=. and example is for separator=/

[listerr]

Okay. But maybe it should avoid using either separator? It's not clear to me why it should be "." - is it supposed to create subfolders representing the source folder of deleted messages, or does it just put all messages in the configured folder, regardless of source folder? Rob

I guess admins like .dotfolders, but practically its just a name so could be expunged too.
