I did an "strace" on one of the hundreds of lmtp processes.
It's doing stat() on all files in the new folder for the receiver:
stat("/var/mail/dovecot/xxxx/xxxx/new/xx.xxx.xxxx.xxxx.com",
{st_mode=S_IFREG|0600, st_size=15505, ...}) = 0
etc.
The "new" folder contains hundreds of thousands of files.
Is there any way to prevent all these stat() calls? It seems like
something there would be an index or cache for?
Seems like it might be due to maildir quota-recalculation?
Yes possibly. But also in order to update the index files.
Seems the use of Maildir++ quota was the problem in this case.
For all I know this should happen only, if the mtime of the directory
changes. Is there some external programm manipulating files in the
new/cur directories bypassing Dovecot? E.g. a rm on command line?
Nope
