In order to return the value from ReceiveMail, you must use "return nm;",
not simply "return:". I assume this is just a typo in your mail, but
SingleThreadModel is one word.

Subject: problem with multiple users changing variables???
> Hi,

> I am having a problem with my servlet that checks the inbox on an imap
> server. I did not have any problems until many users began using the
> servlet. What is happening is that sometimes new messages will be in the
> inbox but the "new mail notification" doesn't occur. I think it has to do
> with the int nm. Maybe one user has set it to be equal to zero and at the
> same time another user is seeing this value of the variable and therefore
> not seeing the "You have new messages" notification. Please look at the
> following segment of code and see if you see any problems with multiple
