Hi,
a customer of ours is having an issue with the smtp proxy in the firewall for one of their applications.
In this application, you can send mails with only a BCC filled in, which they often use... When doing that, and the 'smtp server' in the application is set to point at the Astaro internal interface, the message sending fails. When we use our internal mailserver as the smtp server, which relays all outgoing mails to the Astaro, the message is sent successfully...
No idea if this is 'by design', but I don't recall them having the issue before version 7.5...
Any ideas?
