Hi to one and all;
I have an exchange server that was found to be relaying tons of mail. i have managed to stop the relaying by selecting the following settings in system manager, default smtp connector,Properties,Acess tab,Relay, and select only the list below.
However i now have 90 pop accounts / remote users that can send mail within our domain @*.ie but when they try to send outside they receive a return message into their inbox to say error 18.104.22.168 unable to relay..
I have tryed changing the client settings on these 90 accounts which are a mix of Outlook/ Outlook Express.
by selecting my server requires authentication "which was always ticked" but i also clicked on settings,and selected log on using and i put the username and the password for the relevent pop account.
Now it worked for some but not for many. for some everything worked fine, for others they would be asked for user/pass/and domain before they could send outside our domain.Others were asked for the same info but it would represent the logon box again and again without sending the mail.
I am now very frustrated; any help to find a balance would be great.
