I have looked into the first two problems:
2008-08-25 09:49:07,212 ERROR -Unable to connect to remote host xxx.xxx.com already connected
2008-08-25 09:49:20,837 ERROR -Unable to connect to remote host xxx.xxx.com Unable to log on. Only one connection to a mailbox permitted at a time.
You were partially right, they were problems created by MailEnable. MailEnable will put a lock on the mailbox not allowing any other users to connect to an individual mailbox until the initial connection is closed with a POP QUIT. However I can still see this being an Aware problem as checking the logs and within 3 seconds Aware is trying to connect to the MailEnable server 30 times. This, I don't believe, is my Aware application because we can't control how often our Aware applications try to connect to a mail server.
The authentication issue that I mentioned: javax.mail.MessagingException 553 Sorry, over your daily relay limit
Is something in Aware. I believe this, because I have my user name, password, correct mail server and port entered for out going. Though it doesn't seem to be authenticating before sending the message, and as such javax.mail has a limit of 100 messages before it cuts you off thinking you were a spammer.
Thank you,
Jordan
