Hi,
I've set up a new server and transferred a number of clients to it. I have included atmail in the install. However, when trying to send from atmail I get the following error:
Could not send message to SMTP server. Check you have access to send messages via the server and that all To/CC/BCC addresses are valid\nError: SMTP Server rejected email. Returned:550 authentication required

What could be causing this?
Thanks
Steve Jacobs
 
Thank you scsi. I tried all instructions including running the exim.conf updates, checking exim.conf, and then updating atmail. I have squirrelmail installed and it works fine. Still have same error with atmail.
