DOVECOT : Cached message size larger than expected

Hi all,

I have a issue with a user in the INBOX directory. Dovecot log some errors :

Seems, some mail files are corrupted or some cached are corrupted.
How can I force dovecot to rebuild the cache (if needed ?).

I try the solution of @lnxgeek in the message : Cached message size larger than expected

Hi I am starting to see a lot of these errors on a user: imap(xxx@example.com)&lt;117976&gt;&lt;1kR5ozIDwFxXNjqC&gt;: Error: Mailbox INBOX: UID=1726: read() failed: Cached message size larger than expected (7720 &gt; 4096, box=INBOX, UID=1726) (FETCH BODY[]) Any good ideas as to how to fix this?

But, after moving more than 10 messages, still have a issue in another message.

Showing message of the INBOX in SOGo working well.
Showing message of the INBOX in IMAP (with Thunderbird) only work the fisrt time, without be able to refresh after.

Hope someone can help me to fix this issue.

Regars,

Hi @lnxgeek

Already try this, but after moving twenty mail, still the error on an another file.

The mail are correctly show in the SOGo web interface.
Does it could be a compression error ?

Does it be possible to remove all the dovecot cache somewhere ?
