New email/notify failing intermittantly #1751
Description
Reference:
https://discuss.flexget.com/t/new-email-notify-failing-intermittantly/3306
The issue here seems to be that when sending email the smtp connection is open/closed for each entry. This causes smtp throttling at a number of providers. Example:
2017-03-23 14:26 VERBOSE details test-Watchlist-LQ Summary - Accepted: 6 (Rejected: 0 Undecided: 0 Failed: 0)
2017-03-23 14:26 VERBOSE notify test-Watchlist-LQ Successfully sent a notification to email
2017-03-23 14:26 VERBOSE notify test-Watchlist-LQ Successfully sent a notification to email
2017-03-23 14:26 VERBOSE notify test-Watchlist-LQ Successfully sent a notification to email

We should attempt to keep the smtp connection open until at least the task is complete or longer so that multiple entries send multiple emails under 1 smtp connection.
