There are a number of possible problems. Try sending an email to someone Their mail servers are the tightest out there.

From what you posted, my first guess would be that your IP doesn't reverse-validate to your domain name, and therefore many ISP's will block your mail.

Run a WHOIS on your IP and see if it reverse-validates to your address. Also check your mailserver logs and see if they shed any more light.

Do you have a static IP, where your ISP allows you to run a server?

Does this happen when sending mail to anyone, or only at certain domains?

sendmail relaying denied errors

Thanks for the replay, I did find out that while some users were able to relay messages, while others were not. This had to do with adding the additional domains to the access file. Is all good now. Ciao
