If maildir_use_size_file is set True, are the maildir_tag and
quota_size_regex options necessary? If no, does having them all
enabled offer a theoretical performance improvement?
I am debugging a problem where IMAP reports a different size than du(1)
reports (excluding the same files, of course).
I am using Courier IMAP with Exim 4.33. The maildir file is as
follows:
20971520S,0C
15438488 3179
909 1
Exim is configured thus:
maildir_quota_directory_regex = ^(?:cur|new|\.(?!Trash).*)$
From what I have read of the documentation for Courier, it tallies all
maildir directories except Trash. I'm hoping this is consistent with
the regex in Exim.
To verify with du, I run:
# du -b --max-depth=1 --exclude='spambayes.db' --exclude='.Trash'
21687808 ./cur
512 ./new
512 ./tmp
6144 ./.Sent
512 ./courierimapkeywords
6144 ./.Drafts
21894656 .
This account is pretty much a catch basin for spam, but not
advertised as a honey-pot. Before running these tests I removed the
maildir file and sent a small test email so that it would be
recreated.
I have also noticed that some of the mail files under ./new do not
have a S= suffix. My gut-feeling is this is the cause of observed
inconsistency.
Thank you all very much for reading this. Any suggestions would be
wonderful.
take care,
hank
