|Summary||0005305: Spike of IMAP sessions at first EAS sync|
after the upgrade at SOGo 5.1 (but it may have been there even before) we notice that when a new user setup their iPhone with ActiveSync protocol for the first time we have a peak of IMAP connection on IMAP server (Dovecot) during the initial synchronization.
Currently we have a limit of 50 IMAP session per IP and this limit is reached fast by SOGo. Analysing more in deep these sessions they are doing nothing, probably are open for FETCH and not close after.
Is this intentional or can be limited/fixed?
|Steps To Reproduce|
Setup an iPhone with an Exchange account where the EAS server is Sogo. During the first sync (if you have at least a thousand messages) you will see a spike of IMAP session for this user on dovecot server.
