Could be.  This option in imapd.conf might be relevant:

rfc2047_utf8: 0

If enabled, imapd will parse any non-encoded character sequence in MIME 
header values as UTF8. This is useful for installations that either 
advertise the UTF8SMTP (RFC 5335) extension or receive mails with 
improperly escaped UTF-8 byte sequences. It is recommended that this 
option is left disabled unless there is good reason to do otherwise.


I'd be curious what damage this can do.
In any case, activating it did not solve: I'm still getting "Data format 
error" and bounce.



Still trying the other things.

 bye & Thanks

Increasing metadata data

2020-03-18 Thread Miguel Mucio Santos Moreira 

Dear,

We're upgrading our cyrus version from 2.4.16-5 on Debian 7 to 2.5.10-3 on 
Debian 9.
Our environment is composed for backend, mupdate master and frontend servers in 
a Murder topology.
Following the cyrus imap documentation we're creating new backend servers with 
that new version informed above.
Even with some punctual issues, we're migrating mailboxes successfully to new 
backend server. However we diagnostic this new backend has a huge increasing in 
it's metadata data in comparison with the old ones.
We are in doubt if it is a expected behaviour or not, and if not what could be 
the problem related to.

Thanks in advance.

Respectfully
--
