dovecot - Jul 2018 - Connection closed (IDLE running for 0.001 + waiting input for

Hi,

Just noticed an Android email client called K9 Mail is producing these 
entries in a server's dovecot log:

Jul 11 21:03:28 mx1 dovecot: imap(me at example.org): Connection closed 
(IDLE running for 0.001 + waiting input for 1728.597 secs, 2 B in + 10+0 
B out, state=wait-input) in=353 out=2154
Jul 11 21:03:31 mx1 dovecot: imap(me at example.org): Connection closed 
(IDLE running for 0.001 + waiting input for 1731.069 secs, 2 B in + 10+0 
B out, state=wait-input) in=389 out=1910

I cannot find out what this means after googling.  Any ideas?



Best wishes,
Sophie

K-9 uses IDLE connections to allow instant notifications upon mail receipt (akin
to "push notifications" but without the need for cell carrier-specific
mechanisms).

Nothing to worry about.
