Hello,
The IMAP clients likely transmit a too complex search query with too much
clauses and Lucene refuses to execute such a complex query.
This is what you want! We want the search engine to be protected from denial of
service attacks: this might have been what you noticed.
I'm interested by the IMAP contextual logs especially the MUA declared by the
ID command, the exact search query that triggered the error.

On Jul 18, 2023 12:04 PM, from Mihai Zamfira Hello.
I use the latest version available on github of apache james jpa-guice which is
integrated with LDAP and an external rdbms.
I get the following errors when mobile clients access the account via IMAP. The
emails are downloaded to the phone, but in the log there are errors of the form
below.
I don't know if this is specific only to the Iphone or not.
