Seen problem after xfer command

[Miguel Mucio Santos Moreira]

Hi everybody,

SERPRO (It's an IT services corporation of Brazilian Federal Government) has discovered what was going on about my xfer problem, they had the same situation in their environment.

We've suppressed the Server Information turning the serverinfo parameter off and this was causing the problem. We thought better to suppress it because of security reasons, turning it on (default value), cyrus put a lot of environment information into email header.
Actually the serverinformation parameter only causes problem if it turned off in backend servers (Murder Environment).

During the mailbox transfer the source server does a downgrade of index to version 6 and the destination server does an upgrade from version 6 to 12:
Jan 25 16:35:48 srcserver cyrus/imap[4608]: user.XXXXX.Templates downgrading index to version 6 for XFER
Jan 25 16:35:55 dstserver cyrus/imap[325]: Index upgrade: user.xxxxx.Templates (6 -> 12)

When the serverinfo parameter is turned on, the above information doesn't appear in log file.

I'd like to thank Gustavo from SERPRO for sharing the information, so if someone else has the same problem put the serverinfo parameter on and have the problem solved.

We'd prefer to suppress this information but mailbox transfer is more important than security reasons for now.


See you
