Thanks for this. The problem I'm encountering is that Dovecot renames
files, and does so to their size on disk rather than their uncompressed
size, undoing any corrective action that's been taken.
Yeah. It's a bit difficult to change the automated fixing code to work
properly with compressed files without some very ugly kludges.
BTW. http://dovecot.org/tools/maildir-size-fix.pl has been updated to
work with compressed files also, making maildir-size-check.sh obsolete.
I had a quick look myself - it looks like it would be! Obviously I can't
leave my production system in a state where mail can't be accessed by
some of its users - so what would your advice be to work around this?
I think my options are:-
- Modify and recompile dovecot so that the affected sub is a no-op and
guarantee that filenames will always reflect the uncompressed size of
the message through other means
OR
- Ensure that the sub never gets called. What condition is it that
Dovecot encounters that triggers it to rename a file?
Thanks for you help with this!
