I've tried to send emails from OTRS 3.0.11 over Indigomail (sendmail) on a Windows Server 2008.
The problem is that the receiving Exchange Server doesn't like the email format with slashes. (see quote)
The sendmail command in the sysconfig of OTRS: c:/sendmail/sendmail.exe -i -t -f
As you can see, the receiver is written in two versions of syntax. One with backslash and one without. How can I get rid of the backslash version? The clean version is fine and works.Sendmail LOG:
Sendmail for Windows V3.11 at Tue May 8 14:27:20 2012
Sending mail from test@domain.com to testing\.name\@domain\.com,testing.name@domain.com
Subject: This is a test
Message sent successfully
The email also comes to the receipient, BUT everytime I get a undelivered message back to the ticket system....

Any ideas?
