difficulties sending email to mailing list

J

I am unable to send emails to a large mailing list, and the response I
receive is ' we do not relay <my email address>'. It seems that it is being
blocked because the recipient servers think it's spam. However, my colleagues
are able to send it from the same server to the same mailing lists without
any problems.
I would really appreciate your help.
Thanks a lot
