Hello, All email I have configured in mail transfer from my domain to other domain aren't working.. I always receive a mail back like : This is the mail system at host xx. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system email'at'domain'dot'ch: user unknown. Command output: Invalid user specified. I have this line in master.cf Can you help me to understand why transfer mail aren't working but other mail haven't any problem Thank you
Sorry this is not a good explication... So it's all email I configure in email forward that aren't working right now and give me the error I have mentioned before. Thank you for your help
