I was researching deeper this issue, activated debug logs and when I move a message from one folder to another the message size is different

This is exactly the sizes I see in the maildirsize. But I think these values should be equals.

Yes, they should be equal. I don't know why they wouldn't be. Do your Maildir filenames contain the S=1898 (i.e. the uncompressed size)? Are you delivering mails via Dovecot LDA/LMTP?

Hi,

I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins.

When I list maildirsize file, I get:

1073741824S 17952 16

If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries:

1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1

I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem?

Thanks, Fernando

Hi, no solution just a confirmation of the bug. lz4 compression here.

Clean maildir directory generated with 'doveadm backup'. So S=..,W=.. are correct.

Moving this mail file from inbox to trash: -rw------- 1 maildir maildir 5165 Mar 13 17:01 1394726488.M954102P27201.dev-nc-pxe.sdv.fr,S=7590,W=7640:2,Sa

Hello

This problem should be fixed by http://hg.dovecot.org/dovecot-2.2/rev/30fb6e95b110 but there is also another issue in Maildir+zlib (relating to received timestamp), that I have not found a fix for yet.
