[Dovecot] mbox INBOX out of sync (?)

[Tinguaro Barreno Delgado]

Hello all,

I've running a Dovecot's installation for several years without problems but since last system upgrade (Dec 26) I'm facing a kind of sync issue with the /var/mail/ inbox files.

We have got mobile and desktops IMAP clients (mostly Mozilla Thunderbird). The problem is that /var/mail/ files (mbox) aren't updated: we can delete mail from clients but they persist in de /var/mail, so the same user can see the mail again from other IMAP client.

Logs seems to be correct.

Many thanks in advance.

Best wishes,
Tinguaro Barreno
