I have a 10-user SurgeMail license for a family mail server. The server has 4 active accounts. I often cannot send email because 11/10 users are logged in, according to the error message.
I have a desktop PC, a phone, and a tablet. Each one has an IMAP client. My three devices occupy six IMAP channels on SurgeMail:
Idle IMAP channels
IP Address Elapsed CPU Idle Msgs Cmds Speed User State
SSL xxx.xxx.xxx.207 872s 0s 871 13401 5 0kb/s email@example.com idle_nothread SSL xxx.xxx.xxx.207 1552s 0s 1551 13401 5 0kb/s firstname.lastname@example.org idle_nothread SSL xxx.xxx.xxx.207 3649s 0s 73 2407 358 0kb/s email@example.com idle_nothread SSL xxx.xxx.xxx.207 3677s 0s 75 13401 119 0kb/s firstname.lastname@example.org idle_nothread
Each IMAP channel appears to consume one of my 10 licensed “users”. If I use my laptop, it consumes 2 more IMAP channels, leaving only two available. Sometimes it seems like shutting down or rebooting one of these devices does not clear the IMAP session on SurgeMail.
Recently when I was unable to send a message, I saw 10 IMAP sessions, all of them me, all of them from the same IP address. It appears that each device consumes 2 IMAP channels, and therefore uses 2 of my licensed “user” slots despite all 10 IMAP sessions being for the same user at the same IP address.
What can I do to prevent my IMAP sessions hogging all of my licensed logins?
The license says it is for 10 users, but it appears to really be for 10 IMAP channels. If I am already logged in to an IMAP session, why does sending a message consume yet another “user” slot?
I would have thought that 4 accounts on a 10-user license would never have a problem like this. Must I double the annual license fee to get 50 logins for a 4-user family email server?
SurgeMail’s license terms are misleading, in my opinion. It’s not 10 “users”; it’s really 10 logins, even if they are all the same user.
I am running SurgeMail Version 7.3c3-3.
