Hello,

I'm running dovecot 2.2.5 in Centos 6.4 on EXT4 fs.

I have activated zlib plugin. The incoming mails is compressed. However,
when i try to retrieve the mail using imap I'm getting this error

Aug 25 22:17:31 vrajah-vps5 dovecot: imap(me@<mydomain.tld>): Error: Cached
message size smaller than expected (1464 < 2452)
Aug 25 22:17:31 vrajah-vps5 dovecot: imap(me@<mydomain.tld>): Error:
Maildir filename has wrong S value, renamed the file from /mail/mailbox/
rvijay.me/me/Maildir/.vijay_gmail/cur/1377448276.M960004P32378.vrajah-vps5,S=1464:2,

bzip2 compressed data, block size = 900k

Am I missing anything? any ideas is much appreciated.
