I keep the quoted message complete because the original thread was
posted six months ago. I am top-posting, no comments inside the quoted text.
I plan to write a blog about mdbox oddities but in the meantime I can
tell you that if you store attachments detached in your mdbox storage
the issue is this:
1. You have a 200Kbytes MB m.* file you are currently targeting.
2. You have a new email to store. Lets say it has a 3MB attachment.
3. You have a 2MB mdbox max file size .
4. Dovecot notices that 0.2+3 2, so it will create a new m.* file.
5. When storing the message, it will store the attachment outside of the
mbox, so the new m.* file will be, lets say, 5Kbytes only.
6. Now you have 2 m.* files: one of 200 Kbytes and other of 5Kbytes.
7. Dovecot tries to reuse undersized m.* files, but it is quite
forgiving. I have some private patches to increase its agressiveness.
If you don't detach attachment, you probably have the same issue: when a
new message makes a m.* file to oversize, dovecot creates a new m.* file
and leave the old one alone, so it will be undersized.

Even searching for him in the archives, I have no idea what he thinks is
a problem.
I know I have no issues using mdbox, with 2mb or 50mb rotate sizes.
He's wondering why many of his mdbox files are much smaller than 2 MB.

Hello,
there are copies with different size in 3 mailboxes of the user
sequentially about 3800 emails.
why not something 2MB files?
After the big file m.0034 with 14MB follow very many small ...
