I have a number of hotmail accounts, and some of them keep getting
invalid password and others are OK.

What exactly do you mean? You are a Mac OS X and presumably you are
getting an alert when you try to pop some hotmail accounts.
I'm not familiar with Mac or OS X alerts; nor with alternative
network tools to poke at the server with. With Win, I would be
using something like telnet or better and engaging the server and
giving it the authinfo or whatever smtp/pop transaction 'by hand' or
by script and watching how the server behaves in the transaction.
Then, after my little telnet session, I would see if enabling and
accessing the logs from my mailuser agent's transacting would be
useful. Sometimes you can see what is going wrong in the logs. I
don't know Mac mailuser agents or how well they log.

the user name and password are all correct, but some do
not work Any suggestions?

I always suspect user error rather than magic in these kinds of
issues. The trick is for the user to figger out where s/he isn't
doing what s/he thinks s/he is doing. That is one of the
discoveries you make when you do it all by hand with Win's telnet or
its equivalent, and then look at the config of the mailuser agent.
Sometimes the process forces you to see something errant you didn't
see before.

Mac 10.4.3. When go spamcop mailbox and click on options and then
click on spamcop tools and then configure external pop servers so
thst spamcop will get the mail from those servers, for some of the
hotmail accounts get error message pf invalid password even though
everything is correct - it is only with some of the hotmail accounts
- even deleted them and re-entered and still the same - that is why
it is confusing.

I'd advise you to keep trying, and if you get frustrated try emailing JT
via support[at]spamcop.net. I am seeing no errors on that screen for my
account at present, which accesses six MSN Hotmail accounts.
