This error is due to a bug in dovecot's 2.2.21 zlib plugin. This error has been fixed in release 2.2.26 with the following bugfix (dovecot/core@ff405d5#diff-2a7035ebd29c61c60ae0287bfcafdf23) .

dovecot.2,2,21 zlib crc error patch.

dovecot.2.2.21.zlib-plugin.cache.uid.issue_#129.zip

Dovecot release notes:
v2.2.26 2016-10-27 Timo Sirainen [email protected]

  • zlib, IMAP BINARY: Fixed internal caching when accessing multiple
    newly created mails. They all had UID=0 and the next mail could have
    wrongly used the previously cached mail.
