Hello All, I have been browsing this site for a while and just signed up and decided to Pay subscription to show my support for all the help and effort you provide Moving on, I have a cloud server with RackSpace with Ubuntu 14.10 installed on it. I followed The perfect install method found here. After that I had issues with email, outgoing and incoming, I manged to fix the outgoing by changing myhostname in main.cf and hostname file. The Current problem is I can't receive emails. I tried to email myself from gmail, and got error "Diagnostic-Code: X-Postfix; unknown user: "admin"", so I played around with the dns records and now Im not getting any errors or bounce backs on gmail, but still not receiving emails! 1 last thing is that when i ssh into my server, i get the notification "* Documentation: https://help.ubuntu.com/ You have new mail." Please help me out you guys, I am a semi-noob EDIT 1: I managed to fix the problem by changing the following in /etc/postfix/main.cf:
Maybe a short explanation of your problem: You can not add a domain in mydestinations etting in a postfix virtual user setup that is used for email as postfix expects only domains there that will be used together with linux system users. Therefor the hostname of a server (which gets added there) should always be a subdomain like server1.example.com and not example.com.
Actually Till, it's thanks to your help I managed to fix the problem, I came across an old topic with the same symptoms, where you mentioned this solutions. So thank you for the help, you are the best.
