Postfix: Client host rejected: Access denied

[SilentWarrior]

Hi,

I have Plesk configured to accept Mails in the mail server settings.
I use Outlook Client with port 587 to connect to the mail server and like to send mails.
But I alway get a Access denied. Is it neccassary that all IP's are allowed in the Withelist of the mail server ?

Thanks

What sort of related error in maillog /usr/local/psa/var/log/maillog ?

I think the problem is solved.

Configuration failure by me.

if you remember, can you please tell us what was the configuration failure ?

I'm not sure but I think it was the settings of our firewall and the settings of Outlook.
There are a pop3 proxy and a smtp proxy in our firewall. As I remember I've set Outlook for SSL but in combination with the firewall proxy that not work. So I switched back to port 25 without SSL.
