Hello, For one month I am sometimes facing problems sending email from windows vista or windows 7 with outlook 2007 through courier-imap to qmail-toaster. I switched on the debug logging mode in courier-imap.
For example I want to send an email to three persons and I can see that in the debug log of courier-imap (domain names have been changed) Notice that also email to internal email addresses is sometimes refused. The outlook client immediately receives an error. But the sender is not mailer-daemon but Systeembeheerder (sysadmin). And the report states that not all people have received the message and that I cannot send email through any email account -Via geen enkele e-mailaccount kunt u e-mail naar deze ontvanger versturen.

I reinstalled the whole qmail-toaster mailserver, but the problem remains. I deleted the Office 2007 from the computers and installed it again, but no results. I don't know what to do else. Does anybody have a clue for me? Kind regards, Lukas de Groen
