Hi,
I'm running a mail server with Dovecot 2.3.20 and Apache Solr as FTS
backend.
It seems that iPhone/iPad Mail clients are generating some IMAP
searches, especially on header Message-ID, that are increasing our Solr
I/O load, especially during the night.
Are these kind of queries normal? What are they?
You can find some logs below.
