Can only connect to one email account on server - others don't try to logon.

Greetings,
Just got my Instinct today.
I run my own mail server for all my domains.
I setup up my first Other Pop3 account easily - worked like a charm.
However, when I started to try to add additional accounts on the same server - either under the same domain name or another domain on the same server - I would always get error S7118 on its first attempt to login - saying to check the username/password.

I checked my server logs, and every time I check mail for the first account - I see where the sprint service logs in normally.  However, on the other accounts, the service makes a connection, but never sends the login data - it just makes a connection, then logs out.  I even tried setting up a second account using the servers IP address instead of one of the domain names - but same results.  Sample of mail logs below:

Dec 10 13:36:14 tjwalker pop3d: LOGIN, user=DELETED FOR PRIVACY, ip=[::ffff:66.35.228.134]
Dec 10 13:36:14 tjwalker pop3d: LOGOUT, user=DELETED FOR PRIVACY, ip=[::ffff:66.35.228.134], top=0, retr=0, time=0
THE ABOVE IS THE ACCOUNT THAT WORKS, THE BELOW IS FROM THE OTHER ACCOUNTS
Dec 10 13:37:18 tjwalker pop3d: Connection, ip=[::ffff:66.35.228.134]
Dec 10 13:37:23 tjwalker pop3d: LOGOUT, ip=[::ffff:66.35.228.134]
Dec 10 13:39:04 tjwalker pop3d: Connection, ip=[::ffff:66.35.228.134]
Dec 10 13:39:09 tjwalker pop3d: LOGOUT, ip=[::ffff:66.35.228.134]

I REALLY need to be able to check multiple POP3 accounts on the same server and certainly shouldn't be having this kind of problem - where secondary accounts don't even try to login after making a connection.

Any help would be appreciated.

Greetings,
Do you work for Sprint? I spent over an hour in chat with their tech support after making the original post here. The tech I was working with checked directly with the Instinct support team - their response was that the current version of the Instinct and/or email software only supports one account per server based on the server IP address.  How stupid is that?  Such a very simple little bug to fix.

Basically, once I setup the first account on a server (the sprint email software then translates the domain name into server IP address) - the software says "OK - this is the only username/password you can use for that server", so when you try to setup other accounts using a different user/password - the software says "That's not what you said the first time, so I won't even try it".

I can't be the only small business owner who has multiple boxes on the same server - sales@, support@, etc.

Sprint said this would have to be an update from Samsung - which doesn't make sense since I believe they use a third-party software/interface for the email?

Anyway, if you work for Sprint, and think there is a way around this - I would be glad to setup a test account for you, etc.

Thanks,

Sent you a private message - Thanks.........
