I've had for a long time ispconfig installed only for hosting websites not emails, i've decided to configure an account and test it out, although my mailbox fills in with recurring error mails that contain the following:
This is the mail system at host xxxxx.xxxxxx.com.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to <postmaster>
If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system
<firstname.lastname@example.org>: mail for
localhost.localdomain.xxxxxx.com loops back to myself
And i don't even do nothing, i just configure that mail account on Outlook and do a Send and Receive and tons of those messages come, and i have to stop the service to make them stop.
Also i can configure the account on Outlook and do a test message without having the "my server (smtp) requires autentication", how can i change that?
Thank you for your help.
