I am using dovecot 2.2.13 on a VPS.
One (only one!) of the users is experiencing IMAP disconnections. The
maillog file is full of errors about corrupted transaction log and index

Can anyone help me on this??? I am about to cry!
Don't know, but I can try to give you some information on what I would
check.
1. http://wiki2.dovecot.org/Debugging/Rawlog
to debug the imap connection, there are probably some more information
about the problem of this user.
2. Most of dovecots index files can easily be deleted and dovecot will
create new ones of his own.
So I would check which files are causing the problems and if it is save
to delete them. If it is then delete them and see what happens.

thank you!
