Do a google search on "open relay check". There are many test sites out there.

When I run mailq and see some mails as deffered mails, I run sendmail -v -q and see lot of mails that I can not recognise the sender nor the recipient.

That is the reason I wanted to know if there is a way to check for open relay.
