SmarterMail will monitor the server and see users connecting via the different syncing protocols, including SMTP, IMAP, POP, XMPP, EAS and MAPI/EWS. System administrators can then use this section to drop an user's current connection if they believe too many are being made or resync . Current connections can be viewed all at once (via the All tab) or separated by protocol. It's worth noting that the numbers displayed in each tab (I.e., SMTP, IMAP, POP, etc.) is the total connections, not, say, the total number of users that are connecting. So if the IMAP tab displays a "7", that means there's 7 total IMAP connections, which could be from 1 or more users.
When viewing user connections, and depending on the tab you're viewing, the following columns are available:
- User - The IP address of the user connecting.
- Enabled - When viewing users by protocol, a checkmark indicates the user has that particular protocol enabled.
- IP Connections - The number of connections from the IP address listed. Multiple connections can occur when a user is connecting to their account via email clients spread across multilple devices.
- Duration - For Webmail only, the amount of time the user has been logged in.
- Last Login - The most recent login for that protocol, if one exists.
- Last Authenticated IP - The most recent IP address that was authenticated for the user, for that protocol.
The following buttons/actions are avaiable, regardless of which tab is being viewed:
- Refresh - Refreshes the list of online users.
- Actions (⋮) - Additional actions are available via this dropdown:
- Blacklist - Adds the IP address to the server blacklist file.
- Drop Connections - End the selected user's session.
Regarding connections that appear to last longer than they should, this could be due to a number of reasons. For example, SMTP connections that stay active for hours could be due to multiple people connecting from behind a firewall. These people all appear to connect from a single IP, but they're actually individual connections, one for each user. The firewall simply portrays the connections as being from a single source. In addition, some numbers may always show up as 0. For example, EWS and MAPI tabs will only show connections when users connecting via those protocols are actually attempting to connect and are pulling or pushing a sync. MAPI and EWS don't IDLE like EAS or IMAP, so the numbers will fluctuate or possibly show 0.
