Not able to relay from home.

I have several users that use pop3 and smtp from home
some can send and receive others can not.
they all are setup the same,
they all have the box checked that my server requires auth
everyone of them can receive email while only 3 of them are able to send
email back out.
we have tried just username and password
and domain\username and password
username@domain and password still no changes

any help greatly appreciated.

Many broadband suppliers are preventing outbound traffic on port 25 except
throught their own servers. This is to prevent the further spread of
mass-mailer worms that make use of their own email server to propagate the
virus.
This sounds like that kind of case.
I know for a fact that on Long Island, optimum online is blocking that port.
