[Dovecot] zlib plugin issues

[Vijay Rajah]

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/

Am I missing anything? any ideas is much appreciated.
