I have several VPS with Webmin/Virtualmin and they work fine. But on one i have error when trying to send mail from outlook or other mail clients. I`m receiving mails without problems but i have problem when i try to send mails from the mail client software.

I have try different mail accounts, different domains, different e-mail clients and different ISP. All the time i get the same message so i think is problem with the VPS i have. The strange thing is that i CAN send mails without problem from SquirrelMail ( i have installed ) and from usermin without problem. I have just problems when sending from mail client.
Any idea what can be the problem ?!
