Hello,
I ahave installed a new exchange server 2013 and i have noted the fowlloing two issues
a) Emails with attachement cannot be received from the server, the email is not received neither an error is sending to the sender.
Internally i can send email with attachments to local recipients
b) when i send messages from outlook 2013 all the emails are charactirzied by spam from the receipient, but when i send the same email from owa there is no problem.
Please advise
