Some emails I receive from friends, have a subject that marks them as "***SPAM***", anyone know why?

the system you are using is adding the SPAM tag based on the spam score of the email sent.

the spam score is based on a whole bunch of things, but the main parts are:

1) Subject line

2) The amount of HTML in the email

3) The domain from where they were sent from

There are two ways you can solve this.

1) Add your friends to the white list, or allowed senders list, or trusted senders list - whatever they call it on your email system.

2) RAISE the spam settings in your email system. The higher the number, the less likely things are to be labeled spam. However, this will affect all email, not just from your friends. Not a good idea.

some times if emails are send it to a lot of people, they will get marked as spam.

you might have accidently added their addresses to you spam list. You might want to edit that list if possible. If you are using yahoo you can bring up mail from them and put it in your bulk mailings box and mark it as "NOT SPAM" then you shouldn't have that problem anymore

fantastic in ur mail placing there is an selection you'll get e-mail from commonly used senders in ordinary words examine that selection or perhaps as u were given first direct mail from some sender upload that in junk keep including in few days you'll get rid of all junk senders good success

Because Y!'s SpamGuard thinks they are.

However,you can still filter your emails.
