Hi, Andrew. Thanks for your reply.

Thank you for this. It seems that Cyrus does not automatically create
this file but after creating it manually, it starts without problems.

Thank you! Indeed that was the problem as you will have seen in a
previous message.

Thanks for the reference. I will read it to see the changes introduced
in this new version.

Now I am having this problem when trying to open a folder inside one of
the mailboxes:

----------
Jan 16 10:47:17 mail cyrus/imaps[10794]: Fatal error: Exists wrong 257
256 22 16596
Jan 16 10:47:17 mail cyrus/master[2694]: process type:SERVICE name:imaps
path:/usr/lib/cyrus/bin/imapd age:0.298s pid:10794 exited, status 75
----------

I was not able to find the cause yet. Maybe a problem with repeated
messages (that "257 256" makes me think about that) causes a process
crash? This had never happened to me with 2.4.17. Apparently, it only
happens with that folder. Yesterday I deleted all the messages there
using Thunderbird (they were cron jobs mails) and now I would have to
see the cron jobs that ran today, but I do not see anything. When I try
to open the folder Thunderbird displays a message saying "Server
[mailserver] has disconnected. The server may have gone down or there
may be a network problem". Maybe the information in the folder is in an
inconsistent state for some reason after the upgrade?

Thanks for your time.

Kind regards,
Daniel
