Not really a Linux question, but certainly not off-topic I hope. I had one of my email users complain about getting rejection notices - looking at the original email I notice: To: <'removed at hotmail.com'> I think this should be: To: 'Some name' <removed at hotmail.com> or just: To: <removed at hotmail.com> It looks as if the email addresses are in the Name field in her address book (Outhouse client). I tried finding it in the RFC, but I believe the single quotes around the email address are not legal right? My MTA (qmail) is trying to send a message to @hotmail.com' - which obviously doesn't exist with the single quote at the end. Josh
