Lately Outlook Mail on my Lumia 950 XL which runs Windows 10 Mobile has been throwing lots of notifications regarding my personal IMAP mailbox account having out of date settings. This has been occurring sporadically and becoming quite a pain. Sometimes up to 7 or 8 notifications are generated in the Action Centre within short periods of time. Interestingly my mail account settings are correct and the mailbox is syncing email with no problems. After doing some investigation on the server side I believe I’ve found the cause of the issue and its related to the maximum number of IP connections available to the Dovecot daemon.
